Hi foamers,
I programed a user defined solvor based on openfoam4.0, it can successfully run on single-core processors. But when I try to run it by parallel muti-core processors, the initial temperature became 0 K(it should be 270K).
For some reasons, I cannot upload my tutorials and the source code of the solver. It is a multi-region tutorial. I separate solution domain by decomposeParDict.
I run "decomposePar" to separate the whole domain and run "decomposePar -allRegions" to separate different regions. The decomposeParDict is

Can anyone provide me with some solutions? Thank you very much！

The error message is as follows.The value of TcathodeFluid is true but the calue of TanodeFluid is wrong(it should be the same as the TcathodeFluid ).And in serial, it is true.


Starting time loop

Time = 0.0001

TanodeFluid min mean max = 0 0 0
TcathodeFluid min mean max = 250.15 250.15 250.15
