Hi,

When I restart to solve the boltzmann_argon model, I got some error messages as below:

Failed to find a solution for the initial parameter.

Maximum number of Newton iterations reached.

Returned solution is not converged.

How to tune to get the right results?

(My version is 4.2)

Thanks~

I also have this kind of problem. It is difficult to convengence. Maybe it is related to the mesh size.........How can we solve this problem?...........
