Keeping p constant
 
Hi there,

I don't have a great CFD background. I'm a student and I'm trying to model the movement of air over land. I've been using pisoFoam because it matches the properties of my flow (or so I believe) - however, pisoFoam also solves for p. In my simulation, p should remain unchanged.

I know that fvSolutions specifies the equation solver to use but I don't see any mechanism to not solve for p which makes sense since pisoFoam solves for p. Is there anyway around this or do I have to define a new solver?

I read, in the OpenFOAM guide, that the absolute values of pressure aren't that important... but I'd like to see how the results differ, if at all, if I keep pressure to empirical observations.

Thank you for your time :)
