[Getfem-users] mesh_deformation

Dear Sir or Madam,


Could you please advise how I and deform a mesh according to a displacement field?


I am trying to simulate a time dependent deformation of a cylinder like object using python-interface. After applying stress the object creeps with time.


I think I can just go with many small time steps. In each time step, I would like to update and deform the mesh according to the displacement calculated as a function of time. And the deformed mesh will be an input for next time step.


I can see there is some related information such as (1) ‘getfem_deformable_mesh.h’ in page 18 in  (2) ‘getfem::slicer_apply_deformation’ in . But I can find details examples.


Thank you very much
