total cell area

April 4, 2002, 07:51

Hi,

I would need to use the cell area in subroutine radpro.f. Is this quantity available somewhere already ? (In radpro.f I would like to divide cell volume by cell area....simple task but I would still need the cell area from somewhere...)

Hi, Ossi

You could find this information in the file nom.inc (in the folder ufile). There are inside the list of all variables used in user subroutines.

I looked through the nom.inc but could not find a variable that would give the total cell area. Anybody ?

Well, I have no idea how to do this inside radpro.f, but this seems a little wasteful - doing the same geometric calculations every iteration. You could perform this on the cell and vertex data of your mesh beforehand, and then access this as DATA in radpro.f. Seems like a lot of work to me, maybe there's something simpler in the same spirit....

Good idea except that I am simulating an engine which means that I have a deforming grid, i.e., changing cell areas. So I think I need to compute the cell area every time step. Only knew how...

Sorry, I am also at loss here, maybe support can help?
