Export values of each iteration step for a specific time step by newton method regarding nonlinear problems

General

Dear all,

For the Hyperplasticity tutorial, I am curious about exporting the left hand side value s and right hand side value L of each iteration in a time step. For example, the following pic shows the residual r of each iteration step in “Time step 1”, do you know how to export a and L for the relation r = a - L for these 8 iterations, so that I could get internal force and external force respectively.

Hii Qiong,

I am not the expert but one way to implement custom newton solver whereby you can have control over everything in each NR iteration. You assemble A and L and solves the linear equation in each NR iteration.

you can refer dokken’s tutorial.

Hi Fenil,

Thanks a lot for your suggestion, I’ve tried it by customizing newton solver yesterday, and it worked out.
