Did anyone successfully run snappyHexMesh in parallel on a mesh which has AMI sliding interfaces?

I tried it and by inspiring myself from the parallel snappyHexMesh tutorials... SnappyHexMesh runs without complaining but then the pimpleDyMFoam case doesn't run and complains about something that is obviously linked to a wrong mesh...

Cheers,


-Louis

Thanks Julian. I didn't solve the running snappyHexMesh in parallel problem (my case would run fine when on one processor), so I left it as is and moved one ;-)

Hey Louis,

I,m in the middle of a project and now just stopped at the point of your issue.
the same as your mentioned case i use SHM & of course with some cyclicAMI boundary conditions, But when running simpleFoam(or any other solvers) it just crashes out with errors.
really need your Tips if u managed how to get rid of that.

regards,
Metti.

Hello Mehid,
unfortunately I was never able to run snappyHexMesh in parallel.

maybe I didn't get your problem.

do you have problem in parallel running the SHM?

Yes, when I run SHM in parallel with my AMI case, the solver doesn't run anymore, gives errors. Now I don't remember the details because this is a long time ago. If I run SHM on one processor and then run the case in parallel it all works fine, although the scaling is really not good.
Cheers

So Louis,

may I have the question of how do you make your cyclicAMI BCs?

Do you use "createPatch" to change the type of the BCs to "cyclicAMI" ?

I use createPath in as sequence as this,

Code:
runApplication snappyHexMesh -overwrite

runApplication renumberMesh -overwrite


# force removal of fields generated by snappy
\rm -rf 0

# - generate face/cell sets and zones
# runApplication topoSet -dict system/createInletOutletSets.topoSetDict

# - create the inlet/outlet and AMI patches
runApplication createPatch -overwrite

runApplication topoSet

runApplication checkMesh
with a createPatchDict dictionary containing entries as the following,

Code:
{
name AMI1;
patchInfo
{
type cyclicAMI;
matchTolerance 0.0001;
neighbourPatch AMI2;
transform noOrdering;
}
constructFrom patches;
patches (cropRotor);
}
Good work,
