I have a pump case with multiple meshes merged together, v2406, cyclicAMI. I did this 100x and it's the only thing I do with OF. The consistenly crashes after initialization, in parallel. It runs fine on a single core. What? It crashes after initializing the AMI patches and before "Reading field U" I tried the keepAMI option too (to keep the faces of the AMI in the same processor), doesn't help I join the first lines of the crash too: ```AMI: Creating AMI for source:AMI_VOLUTE_RL and target:AMI_RL_VOLUTE AMI: Patch source faces: 665 AMI: Patch target faces: 1420 AMI: distributed AMI: Patch source sum(weights) min:0.999502 max:1 average:0.999998 AMI: Patch target sum(weights) min:0.861346 max:1 average:0.993113 [64] [67] [stack trace] [67] ============= [stack trace][48] [stack trace] [48] ============= [67] #1 Foam::sigFpe::sigHandler(int)[71] [stack trace] [71] ============= [48] #1 Foam::sigFpe::sigHandler(int)[64] [71] #1 Foam::sigFpe::sigHandler(int)============= [63] [stack trace] [63] ============= [63] #1 Foam::sigFpe::sigHandler(int)[70] [64] #1 Foam::sigFpe::sigHandler(int)[stack trace] [70] ============= [70] #1 Foam::sigFpe::sigHandler(int) in /shared/tec-sw/openfoam/OpenFOAM-v2406/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so [67] #2 ? in /shared/tec-sw/openfoam/OpenFOAM-v2406/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so [71] #2 ? in /shared/tec-sw/openfoam/OpenFOAM-v2406/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so Any idea is appreciated, completely puzzled by why the decomposition would break things now.
