Freefem++ is a open source FEM software, but I am not sure whether it can do large scale deformation analysis of beams!

Thank you Dr Mani S Santhanakrishnan and Dr Abhimanyu Kumar

Hi

Code Aster is an open source general FE code for linear and non-linear problems. It is quite a clever code.

That said, I believe you get all of them + some more if you download a CAELinux runtime DVD. https://caelinux.com/CMS3/index.php/download

Thank you Claes Richard Fredö

Could I run Code Aster on windows? Claes Richard Fredö

Maybe. There is a Windows version but it is not easy to get it to work. Simpler is the CAELinux runtimeDVD.

Thanks Claes Richard Fredö

I would also recommend Code Aster. Although I am not a user of it, I believe that it is one of the best open source FEM codes available.

You can find the windows version here: https://code-aster-windows.com/

If you are pythonic guy, PHENICS is a fantastic option for your need.

Dear Khaled,

Go through PHENICS and FEAPpv with IgA and RVE. Both are good for finite strain deformations. FEAPpv may be good for your deformation solution.

I havn't used the open source codes yet but I think deal.ii and Moose are quite famous in solving FEM related problems.
