Dear all,

I have taken the cylinder tutorial of reactingParcelFilmFoam and ran it sequentially and no problems. Then I did decomposePar for running it on 2 processors. Parallel run started and stopped then with the following error message from each procesor:

[0]
[0]
[0] --> FOAM FATAL ERROR:
[0] Cannot find file "points" in directory "wallFilmRegion/polyMesh" in times 0 down to constant
[0]
[0] From function Time::findInstance(const fileName&, const word&, const IOobject::readOption, const word&)
[0] in file db/Time/findInstance.C at line 188.
[0]
FOAM parallel run exiting


I cannot make any sense out of this message and the usual tricks do not work. Anybody having a similar experience and better a solution.

Thanks.

This solver uses two meshes: one for the (single phase) bulk flow regime and one for the wall film. The mesh for the air space is what is decomposed with decomposePar. To decompose the mesh for the wall region as well, you first need to run
decomposePar -region wallFilmRegion

See the Allrun-parallel script in the HotBox tutorial. The "wallFilmRegion" mesh is extruded from the original mesh.

I want to run a simulation for a complex geometry with a very thin film on the surface. Is there a way to introduce the thin film over a custom surface and solve it as a 3D problem? If so, can we increase the number of elements in the thin film region?

The OpenFoam version I'm using is 17.10

Thank you.

the wall film mesh means that there is another set of equations for the film?
if so ,how can i modify it to fit in my case?

ps: i want to modify a new mass transfer model with the film model
