[FLASH-USERS] artificial viscosity

[Maksim Kozlov]

Dear Flash users,
I would really appreciate it if you help me with the following issue. In
unsplit hydrodynamic simulations one can add artificial viscosity and set
the value of artificial viscosity coefficient. The default value is 0.1. I
was wondering what units are used for this coefficient and what kind of
viscosity it is. Is it dynamic viscosity? What are reasonable range of
values for this coefficient?
Thank you very much!
