Unsteady total pressure
 
Hello everyone!

Does anybody know how to set unsteady boundary condition with total pressure? In other words, I want to specify inlet with varying in time total pressure.
I use OpenFOAM 3.3-cvs.

I too am working on a problem similar to this. I have tried referencing an external file with my pressure values in for each time step, but have had little success thus far. I have tried the following syntax in p:

Quote:


inlet
{

type totalPressure
p0 DataFileName "file.dat"

}
But it hasn't worked. I have tried a number of variations on this, however largely I receive an error about outOfBounds being undefined within p.

If anybody else can help us, that would be fantastic.
