Hi all,

OF Version 7,
solver: reactingMultiphaseEulerFoam

i am trying to run a simulation with the solver reactingMultiphaseEulerFoam. Before that i created 2 meshes, which i merged with mergeMeshes. for the interface i use cyclicalACMI, i already executed every necessary step successfully. i can run pimpleFoam, icoFoam & simpleFoam with no problem, but when i switch to reactingMultiphaseEulerFoam or reactingTwoPhaseEulerFoam, the solver does not even start.
i attached a screenshot.

my question is, is cyclicACMI compatibal with that solver?
or is cyclicalACMI specifically created for certain solvers?

cheers

Edit_1: i found a bug report on that issue: https://bugs.openfoam.org/view.php?id=3052
its not actually a bug, but i think cyclicACMI is not currently supported.
i also analyzed the solvers which can run that internal boundary, e.g. pimpleFoam and interFoam, and they support dynamic meshes.

so i finally fixed it somehow.
the problem was that initial boundary values were not well set for cyclicacmi patches.

Hello Geth,

can you tell me how you fixed the issue?

Best regards,

I cant remember exactly what i did to fix it to be honest, i am working with another mesh now, so i dont have that problem anymore.

Maybe you can describe your problem in detail (what you want to simulate, your mesh, solver, version, why does it now work, what is the error message) and i can try to help you.

Kind regards

Thanks for your reply.

I am trying to simulate a sixth of a vortex tube.
My mesh is made with snappyHexMesh. sHM crashes when the cyclicAMI patches are actually specified as cyclicAMI, so I mesh them as walls and afterwards use createPatch to change them to cyclicAMI. I used many more ways of achieving that. Even when not decomposed, the solver crashes.
I'm using reactingTwoPhaseEulerFoam on OF-v2212.

Error is always:

--> FOAM FATAL ERROR: (openfoam-2212)
Unable to set target face for source face 19081
