Dear All,
I have run into a serious difficulty with interFoam, decomposePar and totalPressure boundary. I have verified that the setup I have runs all right in serial and now I want to run a mesh refined case. Unfortunately after applying decomposePar the boundary conditions for p_rgh change from totalPressure to buoyantPressure. Is this is an intended behaviour? I have tried scotch and simple decomposition with the same result. I have tried various number of processors for decomposition. The problem is that this causes my simulation to break immediately with the following error message: Code:
FOAM FATAL ERROR: [1] Continuity error cannot be removed by adjusting the outflow. Please check the velocity boundary conditions and/or run potentialFoam to initialise the outfl ow. Total flux : 1.026523172e-09 Specified mass inflow : 3.355484345e-11 Specified mass outflow : 3.356035588e-11 Adjustable mass outflow : 0 [1] [1] [1] From function adjustPhi(surfaceScalarField& phi, const volVectorField& U,const volScal arField& p [1] in file cfdTools/general/adjustPhi/adjustPhi.C at line 118. [1] FOAM parallel run exiting Do you have any suggestions or explanations for this behaviour? I would obliged for any assistance. |

What an eclipse...
It turned out that my boundary is defined twice in the original 0/p_rgh directory. The second bc was the one that decomposePar was taking. I am sorry for sounding the alarm needlessly. |
