[Getfem-users] How_to_update_im_data_in_each_loop

[Zhenghuai Guo]

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
