The method to update phi in PDRFoamAutoRefine has been superseded by rhoUf in all other compressible solvers and PDRFoam needs to be updated, requiring funding. PDRFoamAutoRefine is no longer maintained.
PDR test case Step to introduce the PDR fields: 1) Create zero-size patches for wall or/and coupled baffles in the boundary file. 2) Specify the boundary contitions for these patches in the fields. 3) Create the new PDR mesh using the PDRMesh utility.
