Hi,
I have a problem with a openfoam case i want to run, what i am trying to do is performing a simulation of the thermal evolution of the fluid in a pipe surounded by air, but if i try to run my case it doesnít work, what goes wrong is weirdly enhough dependent on how i try to run the case, if i try manualy it gives a warning and a error and if i try to run it with Allrun-parallel it gives other warnings and a other error, but if i try to run it with Allrun-serial it appears to run but it does not get anywhere, for example i ran the case for 15 hours, but the first result hasnít showed up yet, and so it appears to run in loops, if i am wrong please show me, but i would expect that i would at least have the first result after 15 hours wit a i7-8750H proccesor with 6 cores and a case with only 625000 cells, i think the problem has something to do with the boundry conditions

I got this warning with every run i tried
This warning did i get at snappyHexMesh
--> FOAM Warning : Displacement (2.326676e-06 1.125094e-05 -3.009801e-06) at mesh point 6246 coord (0.09072973 0.725292 -0.0627314) points through the surrounding patch faces
Smoothing displacement ...




This warrning did i get with log.changeDictionary.*:

--> FOAM Warning :
From bool merge(bool, Foam::dictionary&, const Foam::dictionary&, bool, const Foam::HashTable<Foam::List<Foam::word> >&)
in file changeDictionary.C at line 304
Reading "/home/stijn/OpenFOAM/OpenFOAM-v2012/tutorials/own_cases/pipe_heat_loss_test/system/air/changeDictionaryDict.boundary" at line 21 to 41
Ignoring non-existing entry minY




when i tried to do the case manualy i got a error like this one

And with log.chtMultiRegionFoam i got this error

--> FOAM FATAL ERROR: (openfoam-2012)
cannot be called for a calculatedFvPatchField
on patch pipeenclosed_internalfluid of field U in file "/home/stijn/OpenFOAM/OpenFOAM-v2012/tutorials/own_cases/pipe_heat_loss_test/0/internalfluid/U"
You are probably trying to solve for a field with a default boundary condition.

in file fields/fvPatchFields/basic/calculated/calculatedFvPatchField.C at line 188.




And when i tried to run the case with Allrun-parallel i got warnings an errors:


This warning did i get with log.redistributePar.reconstruct-*:

--> FOAM Warning :
From int main(int, char**)
in file redistributePar.C at line 2400
Working in decompose or reconstruction mode automatically implies -overwrite

This error did i get with log.redistributePar.redist-air:

[1] --> FOAM FATAL ERROR: (openfoam-2012)
[1] Non-processor patches not synchronised.
Master patch 0 name:inlet type:inlet
Processor 1 patch 0 has name:minX type:genericPatch[2]


And i get this error at log.chtMultiRegionFoam:

--> FOAM FATAL ERROR: (openfoam-2012)
[3] On patch procBoundary3to4 trying to access out of range neighbour processor 4. This can happen if
trying to run on an incorrect number of processors
