Parallel runs with sonicDyMFoam crashes (works fine with sonicFoam)

Hi!
I have problem with running my dynamic mesh case in parallel. Basically sonicFoam works fine for me in both parallel and serial, but sonicDyMFoam only works in serial. It crashes with a floating point exception. I'm running OF version 2.1.0 on Ubuntu. I have tried different decomposition methods (simple, scotch) and different number of partitions. I have also tried the preservePatches option when decomposing since my case contains cyclic patches but without success. It also appears to crash at the same step. Below is a typical log of a crashing run. Does anyone have any idea what causes this? Any help is welcome. / Johan johan@construction-05:~/fsiKlaff/sixDoFKlaff_forts$ mpirun -np 2 sonicDyMFoam -parallel /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.1.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 2.1.0-0bc225064152 Exec : sonicDyMFoam -parallel Date : Mar 09 2012 Time : 10:36:35 Host : "construction-05" PID : 3945 Case : /home/johan/fsiKlaff/sixDoFKlaff_forts nProcs : 2 Slaves : 1 ( "construction-05.3946" ) Pstream initialized with: floatTransfer : 0 nProcsSimpleSum : 0 commsType : nonBlocking sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster allowSystemOperations : Disallowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0.0005 Reading thermophysical properties Selecting thermodynamics package ePsiThermo<pureMixture<constTransport<specieThermo <eConstThermo<perfectGas>>>>> Reading field U Reading/calculating face flux field phi Creating turbulence model Selecting turbulence model type LESModel Selecting LES turbulence model Smagorinsky SmagorinskyCoeffs { ce 1.048;
