[Getfem-users] How_to_update_im_data_in_each_loop

Hi, Konstantinos and Yves  and Andriy,

I add a im_data “previous_cauthy_1” to the model. Then in each step of a loop from 1 to 10, I would like to update this im_data. The code sample is as below. Could you please teach me how to update values of the im_data?


getfem::im_data previous_cauthy_1(mim_1);

model.add_im_data("previous_cauthy_1", previous_cauthy_1);

getfem::add_nonlinear_term(model, mim_1,"(lambda_1*Trace(Grad_u_1-previous_cauthy_1)*Id(qdim(u_1)) + mu_1*(Grad_u_1+Grad_u_1'-previous_cauthy_1-previous_cauthy_1')):Grad_Test_u_1" );


for i = 1 to 10:


 getfem::standard_solve(model, iter, solver_name, ls);


update im_data "previous_cauthy_1", for the next loop step




Thank you very much
