cannot use fvOptions vectorCodedSource in parallel simulation

Sgs · December 5, 2019, 14:44

I can run my simulation on 1 core with my fvOptions file, and I can run the simulation in parallel without my fvOptions file, but I cannot run a parallel simulation with my fvOptions file.

Version: OpenFOAM v1806
Solver: icoReactingMultiphaseInterFoam

I was using the default fileModificationSkew of 10 and which gave a "Cannot read (NFS mounted) library error" (log file attached).

I re-compiled OpenFoam with fileModificationSkew set to zero (re: this suggestion) which gave a "couldn't close stdout: Stale file handle" error (log file also attached).

I tried making the dynamicCode directory available before running decomposePar, and that didn't seem to help.

Each step (blockMesh, setFields, etc.) before the solver starts runs fine in any of the above configurations, so I have only attached my fvOptions file.

Any advice would be greatly appreciated.

Did you able to fix it?

I am facing the same issue. Did you able to fix it ?

No, I gave up on this and created a new solver where I added the term I wanted to the RHS in UEqn.H.

I wanted a sponge-like term so I defined a new scalar field in createFields.H, used the setFields module to set the term to zero everywhere except where I wanted the sponge, and then added

Code:

cmptMultiply(SpongeU,U)

to the RHS of the UEqn.
