[Getfem-users] manually set deformation before compute_tangent_matrix

[Nico Galoppo]

Hi,

Is it possible to set a field on a fem explicitly, such that the
correct state is used when recomputing the tangent matrix?

For example, I would like to set the deformation of the mesh_fem mfu
that was linked to a brick as below:

gf_mesh_fem_set(mfu, 'fem', gf_fem('FEM_PK(3,1)'));
b0 = gfMdBrick('nonlinear elasticity', mim, mfu, 'SaintVenant Kirchhoff');

... setting some constraints in brick b3 ...

Here, I would like to set the deformation of mfu explicitly, to
extract the tangent matrix. Is this possible?

gf_mdstate_set(mds,'compute_tangent_matrix',b3);
gf_mdstate_get(mds,'tangent_matrix')

Thanks!
