cell volume

lg88 · March 27, 2012, 22:42

hello everyone
I have a expression like this:
s=vol*divA
where vol is the volume of a cell.
I hope to implement it just with CEL ,But I don't know how to express vol in CFX.Can you help me?

Thank you very much!

What do you want to do with the function?

Functions like volumeInt() may mean you do not need the cell volume yourself.

Hi
I want to use it as an source term for the momentum equation.But I don't know what volumeInt() mean?
Can you tell me what is the meaning of "Volume-weighted integration of
the variable within a domain or subdomain" for volumeInt().

Why would a source term depend on the cell volume? That does not sound physical to me.
