Hello Foamers,
I created a new motion solver based on the motion solver “mixerGgiFvMesh”. The result is a rotating inner ring which also moves horizontally or vertically. Therefor I rewrote the last lines of the source code of mixerGgiFvMesh: bool Foam::journalBearingMotionSolver::update() //instead of Foam::mixerGgiFvMesh::update() {
} Then I added a pointMotionU-file with the mesh-motion-boundary-conditions and everything seems to be fine for small cases on a single cpu-core. For bigger cases I wanted to use decomposePar, but every time I got an error message like this: Processor 0 Number of cells = 452264 Number of faces shared with processor 1 = 387 Number of processor patches = 1 Number of processor faces = 387 Number of boundary faces = 941279 --> FOAM Warning : From function dlLibraryTable:pen(const fileName& functionLibName) in file db/dlLibraryTable/dlLibraryTable.C at line 86 could not load /home/matthias/OpenFOAM/matthias-1.6-ext/lib/libmyDynamicFvMesh.so: undefined symbol: _ZTIN4Foam13dynamicFvMeshE Processor 1 Number of cells = 452264 Number of faces shared with processor 0 = 387 Number of processor patches = 1 Number of processor faces = 387 Number of boundary faces = 941317 Number of processor faces = 387 Max number of processor patches = 1 Max number of faces between processors = 387 Processor 0: field transfer --> FOAM Warning : From function dlLibraryTable:pen(const fileName& functionLibName) in file db/dlLibraryTable/dlLibraryTable.C at line 86 could not load /home/matthias/OpenFOAM/matthias-1.6-ext/lib/libmyDynamicFvMesh.so: undefined symbol: _ZTIN4Foam13dynamicFvMeshE Initializing the GGI interpolator between master/shadow patches: insideSlider/outsideSlider --> FOAM FATAL ERROR: size of field = 978086 is not the same as the size of mesh = 941670 From function DimensionedField<Type, GeoMesh>:imensionedField(const IOobject& io,const Mesh& mesh, const dimensionSet& dims, const Field<Type>& field) in file /build/buildd/openfoam-1.6-ext-1.6.0/OpenFOAM-1.6-ext/src/OpenFOAM/lnInclude/DimensionedField.C at line 72. FOAM aborting When I erase the pointMotionU-file then decomposePar runs till the end. With this fact and the text of the line “Initializing the GGI interpolator between master/shadow patches: insideSlider/outsideSlider” I come to the conclusion that the ggi-routines don't work with pointMotionU. What can I do to solve this problem? Awaiting for replies! Regards Matthias |
