Thank you for your explanation.
Regarding creep, at the moment I only use liner_elasticity_brick with young’s modulus being changed on each time-step. This is just to start with. I am new in Getfem in fact.
Could you please advise about the follows?
I was trying to see if it is possible to use this function in Python interface by using SWIG or Python.Boost. But it is far beyond my knowledge.
Thank you very much

Dear Zhenghuai Guo,
I don't use Python interface much, but your assumption is correct, using getfem::temporary_mesh_deformator (from getfem_deformable_mesh.h) you can apply displacement field to the mesh.
By default temporary_mesh_deformator will deform the mesh and un-deform it in the destructor, unless you build it with the argument to_be_restored=false.
I only assume that you can do it with Python too.
I'm not really experienced with creep, but intuitively I would assume that you can also use large deformation formulation to account for the change in geometry.
Or it's not how you intend it?
In your follow up email you are asking about the usage of mesh slices. From what I know it's used primarily for post-processing, not calculation. If you intend to use it solely for
post-processing than you can easily achieve it nowadays with Paraview, were you import a vtk file, warp the result with a displacement field and take a desired slice.
