I need a detailed 3-D CAD model of a naval vessel that captures the hull form and propulsion layout accurately enough to feed into hydrodynamic analysis software. Once the geometry is approved, I also want a full suite of seakeeping and maneuvering studies: • Seakeeping: stability analysis, wave-resistance predictions, and motion-response curves in regular and irregular seas. • Maneuvering: turning circle, zig-zag, and stopping analyses so I can benchmark agility against current NATO criteria. The workflow I have in mind is straightforward. First, produce the parametric hull and propulsion geometry in a neutral file format (IGES or STEP) along with native files from Rhino, SolidWorks, or a comparable naval-architecture tool. When the geometry passes my visual and hydrostatic ...

I need a COMSOL Multiphysics specialist (AND/OR Digimat AM) who can help me streamline a selective laser-sintering (SLS) workflow. The focus is squarely on boosting efficiency and speed rather than redesigning the part or inventing a new material. I already run Digimat for micro-mechanical insight, so your COMSOL model should interface smoothly with—or at least accommodate—Digimat data. Scope of work • Build or refine a multiphysics model that captures the thermal, mechanical and phase-change behaviour of composite CF-PA11 during SLS. • Calibrate it with any lab or literature parameters you recommend so the results remain physically meaningful. • Run parametric sweeps on laser power, scan speed, hatch spacing and layer thickness, then identify the best win...

I need a detailed ANSYS-based simulation of the entire gating system for a sand-cast component. The goal is to visualise metal flow from the pouring basin through the sprue and runner network, identify turbulence pockets, pressure drops and temperature gradients, then recommend geometry or process tweaks that will cut defects before we cut tooling. What I will provide: • Alloy and pouring data (temperature, flow rate, mould properties) What I expect back: • The ANSYS project file with all boundary conditions, material libraries and meshing set up so I can rerun it in Workbench • A concise report (screenshots, plots, short commentary) pinpointing flow problems and suggesting practical changes to improve yield and surface integrity • Any scripts or user-defined func...

I need a complete RFEM model and calculation package that shows, step by step, how my steel spiral staircase performs under the factored area loads I will supply. The sole objective is to quantify load-bearing capacity for normal human traffic; furniture, equipment, wind and snow are outside the scope. Please use Dlubal RFEM throughout, documenting every assumption, member property, boundary condition and load combination so I can reproduce or audit the work later. The final package should include the native *.rf5 file, a concise PDF report with utilisation ratios, deflection checks and a short narrative of your approach, plus any spreadsheets you generate. I will provide the architectural drawings, material grades and the factored live-load values. You may follow whichever code you f...

I have an existing model already prepared in native ANSYS format and now need a specialist who can carry the structural analysis through to completion. The focus is exclusively on structural behaviour—load application, boundary conditions, solution setup and result interpretation—so experience with Workbench / Mechanical is essential. Your task is to validate the current model, refine the mesh if required, run the analysis and return clear, actionable results with stress contours, deflection plots and any critical points highlighted. A concise summary explaining whether the design meets the required factors of safety will round things off. Please let me know how quickly you can begin and what information you still need from me; the file is ready to share as soon as we sta...

I have a completed CAD model for structure and now need a qualified Mechanical/Structural Engineer to perform an independent safety review. The goal is to confirm the design’s integrity and readiness for real-world use in harsh Canadian winters. Key points you will assess • Environmental loads: heavy snowfall, extreme cold temperatures, and high winds. • Compliance: all calculations and recommendations must satisfy current Canadian Building Codes. • Structural soundness: verify member sizing, connections, material selections, and any fatigue-critical details. • Practical constructability: flag areas that may be difficult or costly to fabricate or erect. Preferred scope of work 1. Run your own calculations and, if helpful, an FEA simulation (e.g., ANSYS, S...

I am building a small, Pakistan-based engineering team to help me turn early-stage product concepts into fully validated, production-ready designs. Freelancers should have strong background in any of these domains of Mechanical Engineering • 3D CAD Design • Industrial Product design • High quality rendering • Thermal Analysis • Structural Analysis • Finite Element Analysis • Computational fluid dynamics • HVAC and Heat load calculation Should have proficiency in following softwares'  AUTOCAD  SOLIDWORKS  ABAQUS  ANSYS APDL | ANSYS Fluent  MATLAB | SIMULINK  COMSOL Multiphysics  FUSION360 | CATIA

I have two detailed SolidWorks maxilla models—each containing a dental implant in the canine region (one 4.1 mm, one 3.3 mm). Before I can trust any results, the files need to be made fully FEA-ready: clean up the complex anatomical surfaces, repair the current mesh issues, and confirm every small detail is watertight so ANSYS does not complain. Once the geometry is sound, move the workflow into ANSYS. The meshing step must balance both refinement around the implant–bone interface and overall element quality; that dual focus is essential for the occlusal loading I will apply. After meshing, set up a static structural analysis that includes: • A 35 N·cm screw-torque preload on the designated model • Physiologic occlusal forces on both implants •...

I need a quick, clean convergence study run in MSC Apex. Once I send you the model, please: • Solve the static analysis for each level. • Export only the displacement results (no stresses or strains) straight from Apex into one Excel workbook, with a separate, clearly-named sheet for each mesh size. - normal mode analysis as well No report, plots, —just the Excel file with the raw displacement data. If you have Apex set up and can turn this around fast, tell me how soon you can deliver and we’ll get started right away. I will need a few screenshots but they are all specified.

I need a thorough CFD study that compares our current 190 mm external cooling fan assembly with a compact 90 mm exhaust fan for the SIMOTICS M-1PH8 (1PH8186-1FF03-1LA1) servo motor. The goal is to confirm that downsizing the fan does not compromise cooling efficiency and, if possible, to outline any design tweaks that would make the swap viable. Both configurations must be simulated under the exact same operating envelope—ambient temperature range, motor load conditions, and the existing ventilation setup—so the results are directly comparable. I am primarily interested in efficiency, so please place particular focus on airflow distribution, pressure characteristics, and overall thermal performance when interpreting the data. What I expect from you: • A validated CFD mod...
