Hello, I have run multiple simulations with different meshes, and the pressure force on z(the biggest force) the lift force has stayed the same. the drag force the force on the y axis has stayed about the same with its mesh group(standard/hex dominant mesh). I was wondering if someone could double-check these forces and tell me whether they are accurate or close to accurate or not. (look in the incompressible folder)
Thank you for your time, help, and effort,
Frank Lucci
Hello!
As an “outsider” looking at the project, it’s difficult to tell. Do you have any sort of experimental data for this model/a similar model?
In any case, if I understood correctly, you are saying that you ran a mesh sensitivity study, and the results for forces in both lift & drag direction are almost constant between meshes, so that is definitely a good indicative of mesh independence.
If you are interested in the topic, I’d refer you to “Computational Methods for Fluid Dynamics”, chapter 11 (Efficiency and Accuracy Improvement), by Ferziger & Peric.
Cheers
