[Getfem-users] slicer_apply_deformation in python interface

[Zhenghuai Guo]

Dear Sir or Madam,

 

I am using python interface getfem. I install it using the following command:

 

aptitude update and aptitude install python-getfem++ as instructed on http://getfem.org/download.html.

 

I would like to use the function ‘getfem::slicer_apply_deformation(mesh_slice_cv_dof_data_base &)’ as mentioned in the page 84 of getfem_userdoc.

 

Could you please advise how I can use it in python interface?

I did import getfem as gf,  but after that I couldn’t find it in the gf. List.

 

 

 

Thank you very much

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 https://download-mirror.savannah.gnu.org/releases/getfem/doc/getfem_project.pdf  (2) ‘getfem::slicer_apply_deformation’ in http://getfem.org/userdoc/export.html#getfem::slicer_apply_deformation . But I can find details examples.

 

Thank you very much
