compressibleInterDyMFoam
 
Hello everbody!

Is there also a tutorial for the compressibleInterDyMFoam Solver (OpenFoam v1.6) available?

best regards.

Hi!
I'm a quite new "OpenFOAMER". I recently managed to set up a simple case: A pump with sinusoidal piston movement. I can send you my very simple case.

In pumpCompressibleInterDyMFoam case,there is a transportProperties file.
look down!

phase1
{
transportModel Newtonian;
nu nu [ 0 2 -1 0 0 0 0 ] 1e-06;
rho rho [ 1 -3 0 0 0 0 0 ] 1000;
rho0 rho0 [ 1 -3 0 0 0 0 0 ] 1000;
psi psi [ 0 -2 2 0 0 ] 1e-05;
}

phase2
{
transportModel Newtonian;
nu nu [ 0 2 -1 0 0 0 0 ] 1.589e-05;
rho rho [ 1 -3 0 0 0 0 0 ] 1;
rho0 rho0 [ 1 -3 0 0 0 0 0 ] 0;
psi psi [ 0 -2 2 0 0 ] 1e-05;
}

what is the "psi" ? Is that the ratio of pressure and density ? How to decide the value of "psi"? what is the difference of the rho and rho0 ?

could you help me ? thank you !
