Which CFD software should I use?
 

Hello everyone,

I am going to do some CFD analysis for non-newtonian fluid. I will define udf code for velociy and will use "fsi (fluid-solid interaction)" module of the software which I will use. The solid part will be a really complex geometry. I have three options, which one do you guys prefer, and why? Fluent, Comsol or Star CCM+. It is important for me, please advise me about this situation.

Regards,

Is your problem very complex?? If not, go for simpler but flexible tools. consider integrating something in MATLAB. This will speed up your work the most. Check out QuickerSim CFD Toolbox and maybe CALFEM for structures

I recommand you to use starccm+ it's an excellent CFD code with full option for overset mesh to simulate FSI problem :)
