Hi,

I am trying to use potentialFoam to initialise the flow for a rhoPimpleFoam simulation but I get the following error.

--> FOAM FATAL ERROR:

    request for volScalarField thermo:psi from objectRegistry region0 failed
    available objects of type volScalarField are

4
(
div(((sqr(U)|(magSqr(U)+(1e-015*average(magSqr(U)))))&convection(phi,U)))
Phi
magSqr(U)
p
)

From reading other posts I think it relates to the thermosi present in waveTransmissive boundary from the p initial conditions file and that I need to use one of the four options it has suggested but I'm not sure how to implement it and be confident I've not impacted the rhoPimpleFoam model. I started with the LES Pitzdaily tutorial for rhoPimpleFoam in case that is relevant.

Could anyone explain how to fix this potentialFoam error? Or do I need to create a separate model to initialise the flow and then copy the solutions latest time files into the 0 directory for the rhoPimpleFoam?
