CEL for Interface Curvature
Hi,
I'm working in a two phase flow simulation and I need to define a CEL function depends on interface curvature. I have looked for this variable in CFXPre but I haven't found it, so I think I must to define it. I know interface curvature is define by divergence of normal vector pointing from primary fluid to secondary fluid, but I don't know if is possible (and how) to write this expression. Thanks in advance Miguel Baritto 
Is it to be calculated during the solution or for postprocessing? It should be much easier to do it in postprocessing.

Hi Glenn,
I'm using two resistance model for heat transfer between liquid and vapour in stratified two phase flow, so I need to specify interfacial heat transfer coefficient. I need this CEL expression: h=ho*K/Ko, where h is HTC, ho is a referencia value for HTC, K is interface curvature and Ko is a reference value for curvature. I don't know how (if is possible) write K in CEL. Thanks Miguel
