Hello,
How can I obtain "interfacial area" value in a cell with two phases using UDF? Obviously, I'm using multiphase model. Thank you for your reply. |

It's probably a bit late but it might be helpul for other users, too.
There does not seem to be any documentation about it. I believe the following should work if we are talking about the default algebraic interfacial area models (ia-particle, ia-ishii, ia-symmetric, ...): int index = MP_IAD_INDEX(i, j); const real iac = C_MP_AREA_DENSITY(c, t, index); i: index of phase-1 j: index of phase-2 c: cell index t: thread pointer But check this carefully before you use it!

What is the function of the macro "MP_IAD_INDEX," as it is not found in the Fluent manual? Thank you very much.
