Hello,
I am new in openFOAM and I have the following problem. The solver which I want to use is the chtMultiRegionFoam solver. I want to model a water flow around a plate. At the bottom water comes into the fluid domain with a velocity of 1m/s and at the top the water goes out. Left and right side are walls. Its a 2D problem. See the sketch attached. I started with the block mesh and now i have problems in going on. 1. created a block with 10x10x1 2. wrote a file *setSet cellSet solid new boxToCell (4.5 2 0)(5.5 8 1) cellZoneSet solid new setToCellZone solid -> Here i have problems to understand what am I doing. I read another description with doing it with a different definition with teh topoSetDict. I think itīs similar but I am not sure. 3. I need to process the boundary conditions 4. any further steps i didnīt do that at the moment cause i think itīs important to understand what in the previous steps happens. For any help thanks a lot. Regards Michael |

look at chtMultiRegionFoam Tutorials at here
Quote:
1-create mesh by blockMesh 2-create cellSet and cellZone with topSetDict 3-split mesh with splitMeshRegion command 4-set boundary with changeDictionary 5-define solid and fluid zone in constant/regionProperties 6- run your mesh
