Hello Rob,

the Simulation I was asking about earlier started working, now I am on to the next iteration and I get the following error, do you know how I can fix it, or at leat tell me where to look. I am new to this, and I am trying as hard as possible to learn! Thanks in advance.

     The problem F.E.M. Task      has not converged.

 

This is the Error message I get in the Listing viewer. I don't really understand why it has a problem with the evolution parameters. I got a failure earlier and I set them to exactly what the Expert System recommended...
