[Getfem-users] divergence of strain tensor

Dear all,

I am wondering how to calculate the divergence of strain tensor in linear elasticity problem. It involves calculating the second derivatives which could be extracted from the compute_hessian in getfem_derivatives.h. Is there any existing function to get the divergence directly? If not, could anyone tell me what is the order that the derivatives are stored in compute_hessian function? Thanks.
