Dear Zhenghuai,
It indicates that an element has a non-invertible transformation (a completely
flat element).
It should be removed before doing any computation.
Best regards,
Yves

Hi, Andriy and Yves and Konstantinos,
I use gmsh to build a mesh and import in getfem. In the code, I only add the
getfem::add_isotropic_linearized_elasticity_brick(model, mim_1, "u_1",
"lambda_1", "mu_1");
and
getfem::add_Dirichlet_condition_with_multipliers(model, mim_1, "u_1", mf_u_1,
total_outer_bounday_1,"Dirichlet_value" );
When I try to solve the equations, I got

The mesh I loaded has an irregular outer boundary as below. When I change the
mesh to a simple rectangle outer boundary mesh (also from gsmh), the test
program runs ok. Can you please advise, what normally does this error message
indicates? I suppose something is wrong with the irregular boundary mesh. Thank
you very much
