Hello OOFEM community,
I recently looked at OOFEM and it really looks a very interesting code. However, I'm wondering if currently is capable to do some stuff:
- Is it possible to select the method to impose periodic boundary conditions (e.g., Lagrange multipliers, static condensation?). Since with the first, a direct solver cannot be used, while with the second is possible. This leads me to the second question...
- For a linear elastic problem, is it possible to select between a direct sparse solver (parallel?) or in particular the iterative method: preconditioned conjugate gradient?
- Is it possible to export the results in text format: Displacement of nodes (e.g., as list), stresses in each gauss point (and location) in each element, in order to be able to post-process in e.g. matlab?.
- Is it currently to rotate automatically the material coordinate system (like fibre direction, for composite materials?) O you need to rotate the Cijkl (stress) tensor by your self and then input the rotated elastic constants?.
- Is it possible to use parallel computing under OpenMP scheme (shared memory) instead of MPI (Dist. memory?).
I am thinking about using OOFEM for numerical homogenisation of fibre composite materials.
Most likely if all of this is possible and you have a simple example it will be highly appreciated,
Thank you and looking forward to hear from you!.
Best,
