hello
I am confused
my question is in the sample multiregionheterradiation in OpenFoam 2.0.0
what is the relation between dimentions in the blockMeshDict file and the regions in any directhion?
I mean that the volume of regions is not equl to the volume of hex in blockMeshDict,i cannot understand why.
is there any conversion factor?
i can not understand the coordinates in file makeCellSets.setSet
thanks for your attention

the points in makeCellSets.setSet is some how strange but you can create ur mesh easily , you just need to know that:
for creating a box with cellSets,
you need two points which are the points on the main diagonal of box!

hi
I'm using chtMultiRegionFoam and i'm trying to understand the example in toturial.
I don't know how to make regions and I don't know how to make the file
makecellset.setSet
please help me to make the file
thanks

its not hard make ur region by commands below:
to make box :
cellSet regionName new boxToCell (x1 y1 z1) (x2 y2 z2)

which point1 and point2 are the point one main diagonal of box

to make cylinder:
cellSet regionName new cylinderToCell (x1 y1 z1) (x2 y2 z2) R

point1 and point2 are the first and the end of cylinder axis and R is radius

to add two regions together you can use:

cellSet regionName1 add cellToCell regionName2
