Hi

I am running a modified version of the solver twoPhaseEulerFoam. The problem is that i can not understand how to get around the error message i get. I understand at some level that there are some dimensions that are wrong somewhere. however, it seems like the error is in "dimensionSet" at line 142, and i do not know where that file is.


I am trying to simulate a stratified air/water pipe. I have put uniform conditions in the "0"folder. To achieve that, i took away the default inletOutlet boundary condition in the "0" folder. I want this eventually to be a laminar case (100 m pipe-length).


The simulation and the error message i get is the following:

I am not very experiensed in interpreting theese OpenFOAM error messages, so of course any help would be deeply appreciated.
