It depends on what type of simulations you want to do, if it is FSI simulations that are the main type I prefer LS-DYNA. Ansys has been around a long time and can therefore solve a wide range of problems but I would not choose Ansys to perform FSI analysis.

The most user-friendly is Ansys and they have a better community since they have been around for a long time. LS-DYNA is more hands on and might be a little trickier to learn but you have some tutorials and examples on the following Youtube channel: https://www.youtube.com/channel/UCPu...-IouTDXGT2EFiw . The CFD solver in LS-DYNA is called the ICFD solver and it has a gmail group where you can ask questions and some other information can also be found on this page: http://www.lstc.com/applications/icfd/documentation

Once you have learnt how LS-DYNA works I like their way better since it is really easy to change parameters with an text editor, instead of opening the GUI. All parameters in turbulence models are available to edit as well, I think it is possible in Ansys as well but it is a lot harder.

I have free access to Solidworks and Autodesk software, Can I use them instead of Salome because it seems because of Linux you have chosen this software?
For the post processing, is Paraview only for OpenFOAM? or it can be used for any other software? Do you feed and import text files to Paraview?

yes you can use autodesk for geometry but i dont think it does meshing as well.

Paraview supports many softwares. It imports files.

Actually, Autodesk has a software called Autodesk CFD Advanced 2016 and it does meshing stuff. Have you heard about it?
Do you do your meshing in Salome ? I thought OpenFoam has this capability!

I agree with you. It is better to begin with writing one's own code, not just click buttons.

This is a new transitional model that should be added to OpemFoam:
"Prediction of transitional and fully turbulent flow using an alternative to the laminar kinetic energy approach"... it is a better model (improvement if you want) than the k-kl-omega.
