Does anyone know if it is possible to show a convergence plot during a livelink with Matlab? I'm using version 4.4 and matlab R2013a.

Thanks

Hi

I read following article in COMSOL about Improving Convergence of Multiphysics Problems:

www.comsol.com/blogs/improving-convergence-multiphysics-problems/

It says that the error plot should go down monotonically and smoothly. However, I got an error plot in which the curve is not continuous. I attached it to this comment. Is there any problem with this error plot or not? My outputs seems correct but I am not sure about this.

Thanks,
Mohsen

Hi there

You can built a better mesh and try it. Here is an idea to test how good is your mesh.
