I am completing an M-Tech in CAD/CAM and my thesis centres on product design optimisation, specifically through multi-objective optimisation techniques. The goal is to demonstrate how conflicting objectives—weight, strength, cost and manufacturability—can be balanced in a real-world product model and to document the full process for academic submission. The work I still need includes formulating the mathematical model, selecting and justifying a suitable multi-objective algorithm (NSGA-II, SPEA2 or a comparable approach), coding the optimiser, integrating it with a 3D CAD model, running simulations, and interpreting the results for discussion and publication. I am comfortable with SolidWorks and Creo for modelling and would like the optimisation routine written in MATLAB or Py...

I need an experienced CFD specialist to build a robust simulation that captures the pressure distribution along the entire length of a pipe with complex geometry. The working fluid is water, and I will supply the CAD of the pipe as soon as the project begins. For this case the flow will be defined through an imposed outlet pressure coupled with a target flow-rate; everything upstream must adjust accordingly, so the model has to converge cleanly under those boundary conditions. You are free to use ANSYS Fluent, OpenFOAM, CFX, or an equivalent solver, but please outline your intended turbulence model and mesh strategy up front so we can agree on accuracy versus runtime. Transient effects are not expected to dominate, but if you feel a steady-state assumption is insufficient, let me know ear...

I need a detailed finite element analysis that zeroes in on stress distribution within an endodontically treated tooth restored with a Post and Core. The model should replicate clinically realistic geometry, material properties (dentin, gutta-percha, cement, fiber/metal post, core build-up, and if convenient the overlying crown), plus the typical occlusal and lateral load cases. What I will supply • Reference papers, anatomical images, and the loading scenarios I want reproduced. • Any additional clinical notes you may need to refine the boundary conditions. What I expect back • A clean 3-D CAD model ready for meshing. • The fully set-up FEA project file (ANSYS, Abaqus, COMSOL, or a comparable package—use whichever you work fastest in). • High-res...

I need a full-physics CFD model that captures how water boils when gravity is virtually absent, such as aboard the ISS. The set-up must be three-dimensional and treat the problem as a multiphase, conjugate heat-transfer case so solid–fluid coupling is resolved along with the liquid–vapour interface. The core phenomena I want you to resolve are: • Bubble formation • Heat transfer rate • Phase change dynamics Please build the model around water at atmospheric reference pressure, specify all governing equations and material properties, and explain any micro-gravity body-force implementation you use in the solver (ANSYS Fluent, OpenFOAM, COMSOL or a similarly capable tool is acceptable). I expect mesh files, solver settings, post-processing scripts, and a...

Project Description: CFD–FSI Analysis of Flexible Flapping Wing Aerodynamics This project focuses on the numerical investigation of unsteady aerodynamics of a flapping wing with flexible deformation using coupled Fluid–Structure Interaction (FSI) simulations. The objective is to understand how wing flexibility and deformation affect vortex formation, wake evolution, pressure distribution, and aerodynamic force generation (lift and thrust). The study will be carried out using transient CFD coupled with structural deformation, where the wing undergoes prescribed flapping motion and deforms under aerodynamic loads. The interaction between fluid flow and structural response will be analyzed over multiple flapping cycles. Key Scope of Work Perform transient CFD simulations of a ...

I have a moderately complex structure that must be built and tested inside RFEM6. The task is purely structural analysis: set up the full 3-D model, apply the relevant load cases and combinations, run the calculations, and fine-tune the model until all members meet code compliance. Please work directly in RFEM6 (current release) and provide: • The native RFEM6 file with all geometry, materials, load cases and combinations clearly organised • A concise calculation report exported from RFEM6 that highlights governing load combinations, utilisation ratios and any recommended adjustments • A short summary of the modelling assumptions so I can pick the project up later without guesswork Accuracy and clarity are more important to me than slick graphics, so keep the model ti...

I have a gas-liquid separator whose internal geometry needs to be verified before fabrication. The task is a complete CFD study of multiphase flow through the vessel, capturing the interaction between gas and liquid phases. My main concerns are flow distribution across the internals, overall pressure drop, and the resulting phase-separation efficiency, so the model must resolve these three metrics quantitatively. A CAD file of the current layout, design operating conditions, and fluid properties will be supplied at project start. The simulation should be run at the specified throughput, using an appropriate multiphase model (VOF, Euler-Euler, or similar) in Fluent, CFX, OpenFOAM, or another recognised solver, with mesh independence demonstrated. Please include transient behaviour if it ma...
