Just wandering if someone tried to use warp3d and might say something on it.
If I remember correctly, in the early time Warp has 2D plane stress/strain including the graphical interfaces of model generation and plotting results. But I could be wrong, maybe another names or solver.
In case of advanced material models of fracture or damage, why not to use TFEL/Mfront integration with CalculiX solver? Since switching to different solver required to learn something new were not easy and fast in learning curves.
Thank you very much for your comments, they are in accordance with my thoughts so to say.
