Reconstructing cyclicAMI fails

Perfectdark · April 27, 2016, 09:44

Hey,

I'm having problems reconstructing my case with periodic bc (cyclicAMI). The mesh was imported with fluent3dmeshtofoam. It's got some areas where the periodic faces don't match very well, so I needed to run the case with cyclicAMI Interface and 'lowWeightCorrection 0.2'. No problems running the case in non-parallel, but decomposing it fails at the reconstruction of the processors. This is probably because of the bad cells, where the weight is too low:

Code:

AMI: Patch source sum(weights) min/max/average = 0, 1.00154, 0.997058
AMI: Patch source identified 8 faces with weights less than 0.2
AMI: Patch target sum(weights) min/max/average = 0, 1.00066, 0.996335
AMI: Patch target identified 15 faces with weights less than 0.2

The case runs fine, even in parallel, just the reconstruction fails

preserving the patches doesn't do the trick, unfortunately.

Any suggestions for this kiind of problem?
I'M using OF2.3.1

Hi,

Does reconstructParMesh work fine?
