Hi,I am trying to run dieselEngineFoam in parallel. But it crashes at the start of injection. I am using OF 1.6 ext. The setup runs perfectly fine in serial.volPointInterpolation::interpolateInternalField(const GeometricField<Type, fvPatchField, volMesh>&, GeometricField<Type, pointPatchField, pointMesh>&) : interpolating field from cells to points [cfd011:30318] *** An error occurred in MPI_Recv [cfd011:30318] *** on communicator MPI_COMM_WORLD [cfd011:30318] *** MPI_ERR_TRUNCATE: message truncated [cfd011:30318] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort) -------------------------------------------------------------------------- mpirun has exited due to process rank 0 with PID 30318 on node cfd011 exiting without calling "finalize". This may have caused other processes in the application to be terminated by signals sent by mpirun (as reported here). --------------------------------------------------------------------------

Has anyone of you the dieselEngineDyMFoam solver? So far, I was not able to create it by myself. I ve problems to understand the relative and absolute meshflux change which is apparently necessary after a topological mesh change. I would like to use the topoEngineChangerMesh class with it. I m also willing to share my dieselEngineDyMFoam solver, if someone wants to have a look on it.Peter

I ve created a new mesh motion class for engines. Basically it consists of the accordionEngineMesh class for the valve motion and for the piston motion layers are added or removed. It works fine with 1.5-dev, also wit a flow solver (engineDyFoam). Unfortunately with 1.6-ext a problem occcur by introducing a flow solver. U are welcome to use this class. I provide you with a test case. Peter

I welcome everyone who found the way to this group :) Please post your questions and ideas here. We can discuss out projects. I am interest in mesh motion strategies for engines and the simulation of GDI engines.Peter
