Non-Commercial Solar Wheelchair FEA

@daljidel001

With 17 yrs in mechanical design/CAE, I can run your full FEA/CFD workflow using OpenFOAM/CalculiX/Code_Aster only. I’ll deliver accurate loads, thermal, and aero results with clear docs and rerunnable files. To align perfectly: what max payload, weather limits, and solver preferences do you want?

@Rahulsingh5xz

Hello, I’m Rahul Singh from Team Velora. With 3 years of experience in simulation and FEA/CFD using open-source tools, I can handle your solar-powered wheelchair project entirely within platforms like OpenFOAM, CalculiX, or Code_Aster. Please come to private chat to see samples of past structural, thermal, and aerodynamic analyses. I will provide fully reproducible project files, a clear technical report with assumptions and solver settings, and concise recommendations for design improvements.

Hello, I can take your solar-powered wheelchair CAD model and build a complete, fully open-source FEA/CFD workflow using tools such as CalculiX, Code_Aster, Ansys and OpenFOAM—with no commercial solvers or libraries involved. My approach will cover all three core analyses you need: • Structural integrity: I’ll import and clean your STEP/STL geometry, apply the static and dynamic load cases you provide, and run non-linear or linear FEA as required to evaluate stresses, deflections, safety factors, and fatigue-sensitive regions using CalculiX or Code_Aster. • Thermal performance: I’ll simulate heat build-up around the solar panels and battery compartment under normal and extreme weather conditions, incorporating conduction, convection, and solar loading where relevant. Results will include temperature fields, hot-spot identification, and cooling recommendations. • Aerodynamic efficiency: Using OpenFOAM, I’ll run external flow simulations to estimate drag, pressure distribution, and airflow behaviour around the wheelchair to highlight opportunities for improving range and energy efficiency. You’ll receive the full open-source project directories (mesh, solver files, case setups), a clear technical report explaining assumptions, boundary conditions, solver choices, and results, and a short recommendation section summarising design improvements. Everything will be reproducible on any workstation using only open-source tools. Regards, Fares Hassan

Hello — I can run your full FEA + CFD workflow using only open-source tools (CalculiX / Code_Aster for structural & thermal, OpenFOAM for CFD) and deliver reproducible results ready to re-run. What I’ll do: • Structural: static & dynamic load cases, stress/deformation maps, safety factors. • Thermal: PV panel and battery enclosure temperature under nominal & extreme conditions, hotspot analysis. • Aerodynamics: external-flow CFD, drag/lift assessment, flow separation maps. • Mesh strategy, solver settings, convergence checks, and sensitivity notes. Deliverables: Complete project folders (meshes, input files, scripts) runnable on Linux. Concise technical report (assumptions, BCs, solver settings, results). Short recommendations for structural, thermal, and aerodynamic improvements. Guidance to re-run and reproduce results. I prioritise accuracy, documentation, and repeatability in open-source environments.

I will perform structural (static and transient) analyses using Code_Aster/CalculiX with Salome/Gmsh meshing, thermal and conjugate heat-transfer cases with Code_Aster or OpenFOAM coupled solvers as appropriate, and aerodynamic CFD in OpenFOAM; all preprocessing, solver inputs, and post-processing will be scripted so the entire workflow is reproducible. Deliverables: complete project folders and run scripts, mesh and solver configuration files, result datasets, a concise technical report documenting assumptions, boundary conditions, material models, solver settings, convergence checks, and key results, plus a short actionable recommendations section. All work will use only non-commercial open-source tools and include versioned toolchain notes.

Hello, With over a █████ of expertise in data analysis and simulation, I am equipped with the skills necessary to tackle your complex and unique project. Although my forte is primarily in cybersecurity and programming, my general aptitude for problem-solving transcends fields. This adaptability has allowed me to consistently deliver supremely accurate solutions. Given the technical and niche nature of this project, I understand the crucial need for precision, documentation, and repeatability without commercial software or libraries - an area where my competency shall be pivotal. My past experience also aligns well with your requirement for risk management and analysis pertinent to cybersecurity. Evaluating structural integrity and thermal performance while identifying opportunities for efficiency improvement are tasks requiring granular assessment, that I've historically excelled at.I thrive under pressure and understand how essential it is to leverage every potential advantage while assessing load-bearing capacity in various scenarios, evaluating heat build-up under extreme conditions, or optimizing aerodynamic efficiency. Finally, I offer not only the required technical skills but also a commitment to your project's success. Your priorities for this non-commercial endeavor are also my own: clarity, repeatability and employing open-source tools exclusively. Working on this project will present a new challenge for me to tackle, yet Thanks!

Hello, I’m Sumit from Sacesta Technologies, an Ahmedabad-based agency working across SaaS, ERP, CRM, AI apps, marketplaces, and Web3. We handle projects end-to-end with a clear process, fast delivery, and solid QA. Your requirement for a fully open-source FEA + CFD workflow fits well with how we work. While we’re known for platforms like FlexoSpaces (coworking portal with CRM and automation) and HustlerGuys ERP (full operations suite), we also support engineering teams with high-fidelity simulations, data pipelines, and repeatable scientific workflows. Our experience on SeaCatBoats, where we built a 3D configuration system and validated geometry for performance modeling, aligns closely with your CAD-to-simulation needs. Here’s how we’ll approach your project: • Set up a reproducible environment using OpenFOAM, CalculiX, or Code_Aster, strictly non-commercial. • Run structural cases for static, dynamic, and max-payload conditions. • Perform thermal analysis for panel and battery regions under provided weather scenarios. • Execute aerodynamic simulations within the same OpenFOAM workflow and suggest drag-reduction options. • Deliver all source files, solver setups, meshes, scripts, and a clean technical report covering assumptions, BCs, models, results, and recommendations. We take full ownership from requirements to demos and ensure everything is documented so you can rerun or extend the setup anytime. I look forward to collaborating on this project. Regards, Sumit Joshi
