My existing Autodesk CFD model for an air-based fluid flow analysis fails to solve either due to the model itself or the boundary conditions. I need an experienced Autodesk CFD user to step in, review the set-up, identify why the current boundaries are blocking convergence, and either fix the current model or generate a new one (whichever the user prefers) Here is what you will do: • Open the packaged CFD file provided • Inspect inlets, outlets, symmetry planes, and any internal surfaces for conflicts, omissions, or mismatched units as well as material assignments • Adjust or completely redefine the problematic boundaries, documenting the rationale for each change inside the study notes. • Run at least one steady-state solve to prove convergence with traces to scope the area I will be available to help assist with any information and I am eager to learn how to complete CFDs independently. I will provide more technical details on the project alongside more details on the boundary/initial conditions and materials. If all goes well I may have future projects to work on.

Hi there, I would be happy to assist in resolving Autodesk CFD solving and convergence issues. With solid experience in CFD troubleshooting, I can quickly identify root causes and stabilize your simulation for accurate results. Approach: Review geometry, mesh quality, and setup Diagnose solver divergence, residual behavior, and errors Optimize mesh (refinement, skewness, cell quality) Correct boundary conditions and physics models Adjust solver settings (relaxation, time step, convergence criteria) Validate results with stable convergence Deliverables: Debugged and working CFD model Summary of issues and fixes applied Recommendations for stable future simulations Optional optimized setup for faster convergence Timeline: To be determined after reviewing the model. Budget: Open to negotiation based on complexity. Looking forward to helping you get reliable CFD results. Let’s discuss further. Best regards, Arati M.

Hi, Hope you are doing well I can help diagnose and resolve the convergence issues in your Autodesk CFD model by carefully reviewing the setup, boundary conditions, and solver configuration. I have experience troubleshooting airflow simulations and identifying common causes of non-convergence such as improper boundary definitions, conflicting conditions, or mesh-related issues. Scope of work includes opening and auditing your CFD model, reviewing all inlets, outlets, symmetry conditions, internal surfaces, material assignments, and units. I will identify inconsistencies or conflicts, then adjust or redefine boundary conditions as needed with clear documentation of each change in the study notes. I will also run a steady-state simulation to confirm convergence and provide solution traces and key observations. If necessary, I can rebuild the model to ensure a clean and stable setup. Assumptions are that the provided model contains sufficient geometry and initial setup to diagnose issues, and that additional inputs (flow rates, pressures, material properties) will be clarified as needed. I will also explain key steps so you can better understand and replicate the process independently. thanks. Maksim

Hello, I bring over 7 years of experience in Finite Element Analysis and Thermal Analysis to the table. I have carefully reviewed your project requirements and am confident in my ability to assist you. To resolve the Autodesk CFD solving issues, I will start by thoroughly examining the provided CFD file. I will meticulously inspect all inlets, outlets, symmetry planes, and internal surfaces for any conflicts or mismatched units. I will then make necessary adjustments to the boundaries, ensuring proper material assignments and documenting all changes in the study notes. Additionally, I will conduct at least one steady-state solve to demonstrate convergence and scope the area accurately. I am keen on collaborating further to discuss the project details and provide a comprehensive solution. Please feel free to connect with me via chat for a more in-depth conversation.

Hi, Could you share the existing Autodesk CFD file with me? I’d like to understand the current boundaries and setup better. It sounds like there might be some conflicts at the inlets or outlets that are causing the convergence issue. With my extensive experience in Autodesk CFD, I can thoroughly inspect your model, identify the problems, and either fix the boundaries or create a new model as needed. I’ll document all the changes I make within the study notes to ensure clarity. After making adjustments, I will run a steady-state solve to verify convergence and provide feedback on the results. I’m excited to collaborate and help you gain independence in completing CFD analyses! Best Regards: Sahad Ahmed K Mechanical Engineer
