fluid density
 
Hi everybody,

I'm a new openfoam user making the first simulations with simpleFoam. I use Salome for geometry definition and meshing, and Discretizer as a GUI to launch OF runs.

My question is where to find (among the case files) the default fluid density value used. I've have not been able to find where to specify it, nor in Salome nor in Discretizer.

Thank's for your comments,

There is no rho in simpleFoam. It is divided out of the equations.

I understand that introducing NU value, it includes dynamic viscosity and density, so that it is not necessary to introduce RHO.
Thank you, Bernhard.
