Dear Prof. Mathias,

Many thanks for your hints. Grid size variation has no effect on stability. I thought about to capture the moment when crucial error occurs. But what I should do next I don’t know since, for example, in BGK model relaxation time is constant all over the domain. An interesting note that when I apply magnetic field with high Hartmann number, code becomes stable.
kind regards,
