Engine Simulation in parallel

Hi ALL, after a small break I am doing engine simulations again
To my problem (OF Version: 1.6-ext): I ve build from the LayerAR class and from the the accordionEngineMesh class (taken from engineTopoChangerMesh) a new mesh motion class (GDIMesh), which allows moving the valves while using for the piston motion the layering approach. So far this works fine on a single processor. The problem arises when I try to let it run in parallel. I ve tested the two classes independently (LayerAR and accordionEngineMesh) in parallel without any problem. So I assume it should also work in my case. My Simulation crashes with the following error: Code:
[0] [0] [0] --> FOAM FATAL ERROR: [0] Not implemented [0] [0] From function globalTetPolyPatchFaceDecomp::updateMesh() [0] in file tetPolyMeshFaceDecomp/tetPolyPatches/constraint/global/globalTetPolyPatchFaceDecomp.C at line 152. [0] FOAM parallel run aborting [0] -------------------------------------------------------------------------- MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 1. NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them. I ve figured out that when a topological change is performed (in this case layering) it executes the following peace of code (Condition: topoChangeMap1->morphing() == true ) Code:
autoPtr<mapPolyMesh> topoChangeMap1 = topoChanger_.changeMesh(); bool meshChanged = topoChangeMap1->morphing(); // included from "mapPolyMesh.H" pointField newPoints = points(); if (topoChangeMap1->morphing()) { mSolver.updateMesh(topoChangeMap1()); if (topoChangeMap1().hasMotionPoints()) { Info << "movePoints(topoChangeMap1().preMotionPoints());" <<endl; movePoints(topoChangeMap1().preMotionPoints()); newPoints = topoChangeMap1().preMotionPoints(); } setV0(); resetMotion(); } I hope someone could give my some hints about the syntax of this line Code:
autoPtr<mapPolyMesh> topoChangeMap1 = topoChanger_.changeMesh(); Cheers Peter |
