Do you mean that for the visualization purposes?
No. I want to build a simulation of a deformation of a heterogeneous media (i.e. tectonic plate with lineral fault zones ) undergoing deformation for a long period of time. Right now I just trying to understand how to use Sfepy (which seems to be a wonderful tool!). And I don't understand how can I simulate actual deformation of a mesh at each of the steps.
You seem to need a large deformation formulation - check the examples in examples/large_deformation/ directory. Specifically, check the examples/large_deformation/hyperelastic_ul.py example, that uses the updated Lagrangian formulation - the mesh is automatically updated in each time step there. If you need to handle the mesh deformation yourself, let us know.
