Default Commercial software question (user viscosity)
Posts: n/a
Hi All

I have a pretty simple question. Do any commercial CFD software package allow for a user viscosity subroutine where the gradient of a user scalar variable is passed as an argument? I have a viscosity that is

mu=mu(T, |grad(c)|)

where c is a user scalar variable that is to be solved for as well.

Thanks Jeff

I would think any of the major codes would allow this. Certainly STAR-CD can, and I'm sure it's not unique in this respect.

Hi Richard,

Thanks for getting back to me. In fact, I may have access to STAR-CD. If you are familiar with user viscosity functions, could you list the argument list to the function? I'll try to track down some manuals.

Thanks Jeff
