hello,

I'm sorry I thought that would work.

You have an old post with the same topic: http://dev.spis.org/projects/spine/home/community/forumsPages/spis/79425723c0a8001401f97e0e5946fcdb You can try to do the same

Regards, Nuno

I tried higher values, but it doesn't work, Newton did not reach convergence.

I dont know what happend.

Nuno, I change iterNewton from 50 to 200, but it doesn't works. I'll try with higher values.

Thanks, Juan Pablo

Hi,

I believe this means that you should allow more iterations to the Newton method when solving the non-linear Poisson equation. You can do this by increasing the value of the iterNewton parameter in the "Poisson Equation" tab in GlobalParameters. Check if that works.

hi,

When simulation is running appear folowing message:

WARNING: Newton did not reach convergence.

What is wrong? how do i solve this problem?
