Hi all, i am trying to solve a problem with OpenFOAM, but it returns the following error:

Anyone can help me to recognize where is the problem?

The solution diverges.

You should at least read the rules of the forum and how to post information about your erros.

Give us a description of your case, your boundary conditions, the type of mesh, the schemes used and then we may help you.

It would be easier if you upload your case.
