1 Mesh setup
The mesh was generated with ICEM-HEXA and exported in the Fluent mesh format. The mesh is generated in two parts: impeller and diffuser, which can be seen in Figure 1.
Figure 1: rotor mesh (in blue) and stator mesh (in red)
This 2D mesh has 93886 hexahedra cells.
To learn more about doing a 2D simulation, see HowTo: 2D simulations
2 Running the case
This case is computed using the GGI interface between the impeller and the diffuser.
Follow these steps to run the case from scratch:
First make sure that you have the following installed:
- A recent revision of OpenFOAM-1.5-dev
- libOpenFOAMTurbo.so (needed for the inlet boundary condition)
- the solver turbDyMFoam compiled
- The boundary condition turboWallFixedValue compiled
- libsimpleFunctionObjects.so (or comment out the trackDictionaryContent function from ECPMixerGgiFvMesh2D/system/controlDict)
- libsampling.so (or comment out the ggiCheck function from ECPMixerGgiFvMesh2D/system/controlDict)
cd $FOAM_RUN/ercoftacCentrifugalPump/cases/MRFSimpleFoam/ECPMixerGgiFvMesh2D
The method of parallel computing should be used in this case, the first step is to decompose the domain using the decomposePar utility as following:
decomposePar >& log_decomposePar&
After the decomposePar finished, the parallel running in this case comes as following:
mpirun -np 16 turbDyMFoam -parallel >& log_turbDyMFoam&
After this case has been run in parallel, it can be reconstructed performed by the reconstructPar utility as the following command:
reconstructPar >& log_reconstructPar&
3 Post-processing the case
The post-processing is automatized, and can be executed by doing:
cd $FOAM_RUN/ercoftacCentrifugalPump/cases/MRFSimpleFoam/ECPMixerGgiFvMesh2D/postProcessing ./Allrun >& log_Allrun&
Likewise, if needed, the post-processing can be cleaned up by doing
cd $FOAM_RUN/ercoftacCentrifugalPump/cases/MRFSimpleFoam/ECPMixerGgiFvMesh2D/postProcessing ./Allclean
This deletes all the data that have been calculated from the post-processing, so be sure that you do not want to save anything from the previous calculation before cleaning up the post-processing.
