Open Source FEM Solver

Open Source FEM Solver

Open Source FEM Solver

There is another recent thread similar to this, but I am looking for something that is very simple.

I only need to solve 2D plane strain/stress problems where I would create the input deck with Excel and a text file.  I would then read the output back into Excel.  Orthotropic material capability is needed.

Since I don't need a pre and post processor, there might be a simple solver that could do this in fortran.  

I am thinking the input deck would look something like that for Nastran.  Actually, now that I think about it, Nastran (the original) is open source and may do the trick?   


RE: Open Source FEM Solver

Not sure exactly the terms of use, but the fortran source is available for FEAPpv is available.

RE: Open Source FEM Solver

It looks like an interesting software, but I don't think I will be able to redistribute it for professional use (from what I can see).  

I have been looking at SAP IV recently, but it only supports isotropic materials, so it won't work.  

Thanks though.  I may email the owner just to be sure.
