Hallo again.
To find the cells containing the interface in interFoam I'm currently thinking about something like this. If (gamma-0.5) has a minimum-value, than there should be the cell containing the interface. min(gamma.internalField()[cellI]-0.5) Well, how can I check if this min is true? I think the coordinate of the cell containing the mininum can be accessed by .mesh().C()[cellI] ? Any ideas?

Hallo,
min will return the global minimum of a field, when I want to do something like that I usually use the pos and neg functions. i.e. pos(gamma-0.5) will return a volScalar field that is zero if gamma is less than 0.5 and 1 otherwise. neg(gamma-0.5) would return a 1 if its greater than 0.5. You can then loop through the field and pick off the cells equal to 1. -Nat |

You mean I should loop through the field an pick the cells where pos(gamma-0.5) and neg(gamma-0.5) both are equal to 1 ?
Or did I get it wrong?
