Hello,
I am simulating a fluid using /MAT/LAW6 HYD_VISC and STIFF-GAS equation of state. When setting the kinematic viscosity Knu to zero, the simulation would run just fine. I tried to look in the documentation for a default value for Knu, but there doesn't seem to be any. I run multiple simulations changing the value of Knu but couldn't get a similar behavior to the case Knu=0. Could you tell me what happens or what does it mean when setting Knu to 0?
Thank you in advance
