I will provide DXF drawings for several serpentine interconnect geometries and need a full non-linear finite element study that zeroes in on their load-bearing capacity. The work starts with layered-shell models to screen all designs, then moves to local 3-D refinement wherever strain or stress peaks appear. Scope of the simulations • Uniaxial tensile loading to global engineering strains of 10 %, 20 % and 30 % relative to the initial end-to-end length. • Additional runs that rotate the load direction so any anisotropy in response is captured. • Large-deformation material and geometrical non-linearities must be included. Key outputs for every geometry • Force-displacement curves and the effective axial stiffness. • Maximum principal strain in materials • von...

I need a full 3D mechanical design for an advanced car shade that will be installed on the car roof like a luggage rack. The final docs should provide the material lists and construction details Shop drawings.(cut lengths and welding) and assembly drawings. The whole shade will be construced by solar panel. The size and weight of it will be specified upon the commencement of the job. The full retraction, expansion, mechanism and the cable tray routes needs to be simulated. A full 3d simulation of the final design and visual presentation of retraction and expansion should be provided without any clash as a result of the engineering job. Key requirements: - Material: Aluminum - Functionality: Automatic extending and retracting - Additional Features: Solar panels and wind resistance...

I need a skilled Ansys HFSS user to run full-wave simulations on an antenna design and provide clear Return Loss (S11) results. This is a simulation-only assignment—no fabrication or physical testing for now. What I will share • Geometry or sketches of the antenna and the target frequency band. • Any material data or performance goals I already have. What I need back • The HFSS project file (.aedt) with all boundaries, excitations, and mesh settings correctly defined. • A PDF or image plot of S11 versus frequency that clearly shows the return-loss performance across the band. • A brief note (one page is fine) explaining solver settings, boundary conditions, and any tuning steps you took. At the moment, the exact antenna style is open; experience ...

I already have a working MATLAB model that generates particles, defines the micro-channel geometry, and steps the simulation forward, but the trajectories are drifting away from the intended channel centrelines. Your task is to bring those paths back into proper alignment with the device. What I need • Correct the alignment of particle trajectories by adjusting the entry points and modifying particle flow direction within the code. • Tackle the root cause: the current channel geometry parameters are influencing the solver in a way that deflects particles, so the fix must happen where those geometric terms are fed into the velocity field or boundary conditions. • Return a clean, well-commented .m file (or set of functions) that reproduces the corrected behaviour, plus ...

I am building a grid-tied solar inverter and need a seasoned embedded designer to deliver complete, production-ready firmware for both an STM32F103 and a TMS320F28035. The inverter must connect seamlessly to the grid, track maximum power from the panels, report its status remotely, and shut down safely if it detects islanding. To achieve this you will configure and optimise the following on the STM32: • ADC – fast sampling of panel and grid voltages/currents for control loops • PWM – generation of high-resolution switching signals for the full-bridge stage • UART – bidirectional link for remote monitoring, logging and field updates On the TMS320 you will implement the high-speed control algorithms (MPPT, PLL, anti-islanding logic, grid-synchronis...

I need a Codesys-based PLC program that will drive an automated piece of machinery using electronic gearing in full closed-loop mode. The machine relies on incremental encoders for position feedback and must maintain tight speed control while keeping several axes perfectly synchronized. Here is what I am expecting: • A clean, well-structured Codesys project that implements electronic gearing and closed-loop PID control for each axis. • Reliable speed control logic proven in simulation or on actual hardware, with clear evidence that synchronized axes never drift. • Parameter blocks and comments that make it easy for my maintenance team to tweak gains, limits, and following error thresholds. • A short commissioning guide describing the start-up sequence, diagnost...

I need an engineer who knows ETAP inside-out to build and run a full fault-current model of my power system. The single-line diagram is ready; what’s missing is a cleanly-configured ETAP file that captures all protective devices, conductor data, and transformer parameters so I can see worst-case fault duties before equipment is ordered. The task centres on: • Setting up (or sanity-checking) the short-circuit module, clearing any data inconsistencies, and choosing the correct ANSI / IEC calculation options. • Delivering a concise PDF and the native .etap file that lets me trace each bus, breaker, and transformer contribution. I’ll provide the drawings, manufacturer sheets, and any utility data you need. Please highlight any data gaps early, walk me through the mo...

I need a detailed heat transfer analysis using ANSYS fluent for a 3D model. The focus is on thermal management. Key requirements: - Expertise in ANSYS fluent , specifically in heat transfer simulations. - Proficient in 3D modeling and analysis. - Strong understanding of thermal management principles. Ideal skills and experience: - Background in mechanical engineering or related fields. - Previous experience with similar heat transfer projects. - Ability to provide detailed reports and insights. Please share relevant experience and approach.

I’m looking to build a clear, well-documented MATLAB simulation that captures the behavior of a mechanical system from first principles. The work is simulation-focused—no data analysis or algorithm research—so every effort goes into translating the governing equations into an executable model that I can run, tweak, and extend later. Here’s what I have in mind: the system’s dynamics will be coded in MATLAB (plain .m scripts, Simulink, or a mix of both if that proves cleaner). I’d like the model to accept key physical parameters as inputs, solve the differential equations with an appropriate solver such as ODE45 or its stiff counterparts, and then generate intuitive visual outputs—plots of displacement, velocity, energy, or an animation if practical...

I need a complete CFD study that shows how an air-cooled lithium-ion battery pack behaves under load. Your simulation must cover three linked aspects—heat dissipation, temperature distribution throughout the cells and channels, and the resulting fluid-flow characteristics inside the cooling passages. Air will be the only working fluid, so model its thermo-physical properties accurately across the expected temperature range. Please apply the following boundary conditions exactly as stated: • constant temperature at selected casing surfaces (representing contact with a chilled plate) • constant heat flux from each cell core • adiabatic walls on all remaining faces I am interested in clear, actionable results: temperature contours on every cell, velocity vecto...

I already use DIgSILENT PowerFactory on an intermediate basis, yet I want to move confidently into advanced territory. My priority is a one-to-one, in-person program that dives deep into: generator start-up modelling and control sequences, detailed transient analysis, and full-system simulations that blend both topics into realistic case studies. We will meet on-site (either at my facility or a mutually convenient location), so I can follow your screen, replicate each step on mine, and immediately test what I learn against my own project files. Expect plenty of back-and-forth questions—this is meant to be conversational and practical rather than a lecture. By the end of our sessions I should be able to: • Build and validate a complete generator start-up model, including protec...

Hi I will share the details with the shortlisted candidates. Thanks

I’m finalising a Delta PLC installation and need a specialist who can write Structured Text in ISPSoft for precise positioning control. The project drives three kinds of loads—conveyor systems, robotic arms and individual servo motors—so the code must coordinate multi-axis moves smoothly while keeping everything in sync. Your program will read limit switches, encoders and proximity sensors in real time, trigger homing or safety routines when required, and leave motion parameters easy for me to adjust later. I’ll share the hardware map, timing charts and target cycle times; you turn that information into modular ST blocks, simulate them in ISPSoft, then guide me through a live download and test over VPN. Acceptance criteria • ISPSoft project file with fully ...

I need an experienced crossover designer to create a passive network for a pair of home-audio loudspeakers that will serve as the front channels of my home-theater setup. Time is critical—I’d like to move straight from concept to components as soon as the design is proven on paper (or in simulation). You will receive the driver datasheets and my raw on-axis/30° measurements the moment we open a workspace. From there I expect you to: • model the network in XSim, VituixCAD, or equivalent software, • refine it until the summed response, phase alignment, and impedance curve all fall within standard hi-fi tolerances, • deliver a clear schematic with exact part values, plus a short bill of materials that I can order immediately. Please include any questions ...

I have a reaction-timing system schematic that needs a careful second set of eyes. Your task is to validate the entire power section—specifically the voltage levels, current-carrying capability of each rail, and how the various power sources are integrated—and then scrutinise every ceramic capacitor on the board for correct capacitance values and voltage ratings. You’ll receive the full PDF and the original design files (KiCad). I expect clear, pin-referenced comments on the schematic plus a concise report outlining: • any mismatched voltage rails or trace width issues that could limit current • potential inrush or stability concerns tied to the chosen power sources • capacitors whose stated capacitance or voltage rating doesn’t align with the c...

I need a precise CNC program created in Fusion 360 for a milling machine cutting steel parts. The model geometry is ready; I will provide the STEP file and a simple drawing that shows critical tolerances and surface-finish notes. The task centers on: • Generating efficient 2.5-D and 3-D toolpaths suited to steel, balancing cycle time with tool life • Selecting appropriate tooling, feeds, and speeds for my Haas VF-series mill (8 k RPM spindle) • Supplying a clean, proven G-code file plus a setup sheet with tool list and operation order All toolpaths must simulate without collisions in Fusion 360 and post successfully to the Haas NG control. If you have suggestions on fixturing or minor model tweaks that could improve machinability, I’m open to them. Onc...

My current AnyLogic simulation is fully built and already addresses data flow and data-leakage scenarios, yet a handful of functions are misbehaving and a few code fragments are still throwing intermittent errors. I want to concentrate first on improving these functions, with special attention on the user-interface interactions that trigger or display key data-flow events. Here is what I need from you: • Debug the existing Java code inside the model, remove the residual errors, and streamline the logic behind the UI-driven blocks. • Refactor or redesign any function that currently hampers smooth data flow or that could accidentally mask leakage signals. • Once the fixes are in place, walk through the validation steps I have already carried out, confirming that my test ...

I’m building a dynamic model in Aspen HYSYS and need a sharp second set of eyes to get the simulation fully set-up and running smoothly. The core flowsheet is drafted, yet several unit operations still require proper dynamic parameters, controller configuration and convergence tuning. I’d like you to jump in, review what’s there, finish the remaining specifications and make sure the case transitions cleanly from steady-state to dynamic mode without warnings or calculation stalls. To keep things efficient, please tell me about your direct, hands-on experience with Aspen HYSYS dynamic simulations—years of use, the kinds of processes you’ve modelled, and any special areas of expertise (e.g. columns, compressors, flare systems). No need for lengthy proposals; a c...

I want a MATLAB-based system-level simulator that models Conditional Handover as well as L1/L2-triggered mobility in an integrated 5G terrestrial and satellite network. The sole purpose is performance analysis, so every module needs to expose parameters that let me compare handover success rate, latency, and throughput across a variety of mobility scenarios. The framework should let me define heterogeneous cells (gNBs and satellite beams), user mobility paths, channel conditions, and decision thresholds for conditional handover. Results must be traceable: at the end of each run I should receive time-stamped logs of mobility events together with aggregated KPIs and visual plots produced directly from MATLAB. Key functional points to cover • Support both 5G NR radio links and a repr...

I’m preparing an electrical simulation in XSim and could use an experienced hand to get everything running smoothly. The immediate goal is to build and validate an audio-amplifier circuit, but I’m hitting a few snags while configuring the project and debugging unexpected behaviour in the tool. Here’s what I need from you: • Walk me through the full simulation setup in XSim—component selection, net-list creation, stimulus definition and any must-have parameter tweaks for audio work. • Identify and resolve the software glitches or warning messages that keep interrupting my runs. • Share practical tips on result interpretation so I can quickly spot distortion, gain issues or stability problems in the amplifier stage. We’ll collaborate live i...

I need a PCB designed for a custom rectangular LED array using through-hole LEDs. The array will contain between 60 LED's. With 2 power inputs. On power being applied to one channel, all of the LED's will light. When power is applied to the other channel, only a selection of LED's will light. There will be a scenario where both power supplies are active at the same time so this will need to be considered. Key requirements: - Design a PCB to accommodate 50-100 through-hole LEDs in a rectangular layout. - Ensure proper spacing and connections for reliable functionality. - Provide Gerber files and schematic diagrams upon completion. Ideal Skills: - Experience with PCB design software (e.g., Eagle, KiCad). - Knowledge of through-hole LED specifications and requirements. - Att...
