Convergence problem with Comsol 4.3b

Please login with a confirmed email address before reporting spam

Hi Everyone

When I run the model in the 4.3a, it can work very well. The convergence firstly is about 1e4 to 1e5. When the comsol software is updated from 4.3a to 4.3b, the convergence becomes 8e8 and cannot work. Does anybody have the same problem? or Does anyone have the idea how to deal with it?

Best wish
Di

I have a similar issue. The model I created in 4.3a does not converge in 4.3b. The termination seems to have a problem. Have you solved this problem?
