Unhappy Same calculation, Different result.

The calculations that had previously converged are still being performed. However, the result is different. It is diverging at a certain point in time. Even if the boundary condition or the resistance value is specified differently, it radiates in the same place. It is hard to understand that the same file is run but the results are different. Have you ever experienced this situation?

You can't run the same file twice and get two different answers, something has changed between them. Do you mean you are extending a certain run? If so it's certainly possible for a seemingly converged run to diverge later. You will have to give more details (and some pictures) if you want more help.

Hello. Yu

I also found the same situation many times..
Sometimes CCM+ predicts different result.
If the cases have the same MESH and PHYSICS.
(almost all people don't know this problem...)

If you want to talk about this problem.. send me a message.
