BFC cell geometry definitions

Olof Liungman

Hi!

I use results from PHOENICS to calculate particle spreading in another software (BFC grid). I run into problems when I try to construct general routines for calculating where in a cell a cartesian position is, in which cell a cartesian position is, etc. My question is: how does PHOENICS define a cell wall in BFC, if the four corners are not on a plane? What about the cell volume?

Thanks,

Olof
