Hey all!

I'm having problems solving a case where the simulation suddenly stops because the global courant has an absurd increase in number.

I'm running a Multi-species, multi phase problem with species transport active, using the Euler model with Multi-Fluid VOF active.

The issue is, after some time steps, even with converge in residuals, the global Courant jumps from around 2.5 to about 18000, from one time-step to another.

Do you have any idea what might be the problem?
