| Summary | 0000704: parallel running error with cyclic BCs for pimpleDyMFoam | ||||
| Description | When I use pimpleDyMFoam together with cyclic boundary conditions,(actually I use waveDisplacement, you can try the movingCylinder case, with a pair of cyclic boundaries and oscillatingVelocity for the cylinder, the same thing happens) parallel running cracks: after about 2 or 3 timeSteps, running stopped with the message " face o area does not match neighbour by 0.0195% --possible face ordering problem", no matter what kind of decomposition method I use, the same problem always appears. But when I use a single core to run it, no such problem happens. So I assume there might be some bugs in parallel running of dynamic mesh cases with cyclic BCs. | ||||
| Steps To Reproduce | Run the following applications in turn: blockMesh decomposePar mpirun -np 2 pimpleDyMFoam -parallel # It cracks! | ||||

Just to share my findings on this: 1- The (almost) latest 2.1.x from commit 0eb2250690e3090f340899d1d8177eed0880301c, locks up instead of crashing. 2- Changing to cyclicAMI (+ a few needed adjustments) should make the case work in parallel. Example available here: http://www.cfd-online.com/Forums/openfoam-bugs/109854-parallel-error-cyclic-bcs-pimpledymfoam-trouble-resuming-running.html#post398703 |

Fixed in 0df303480d00a3bd9773c7b9c28ad57cb201a3d6 It was probably working for 'blocking' commsType. It now works for nonBlocking as well. It should now also handle multiple cyclics between the same two processors. Thanks for reporting. |
