chtMultiRegionFoam Set-up
 

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 it´s similar but I am not sure.
3. I need to process the boundary conditions
4. any further steps i didn´t do that at the moment cause i think it´s important to understand what in the previous steps happens.

For any help thanks a lot.

Regards Michael

look at chtMultiRegionFoam Tutorials at here
steps are as followings:
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 ;)

Hi Michael!

Take a look at this link, please: http://openfoamwiki.net/index.php/Ge..._-_planeWall2D

Try to read and understand the whole process step by step, it's a really useful tutorial!
