Hello everyone,


I am trying to calculate the vorticity for a two-phase flow, however the post processing function is designed for single phase, can someone advise how I can use it for a two phase flow?


postProcess -func vorticity


I get the error cannot find U fields, which is true because i have U.air and U.water



Thanks!

Haven't tested it though but something like this in your controlDict should work

vorticity_AIR
 {
 type vorticity;
 libs ("libfieldFunctionObjects.so");
 writeControl timeStep;
 writeInterval 100;
 U U.air;
 }


vorticity_Water
 {
 type vorticity;
 libs ("libfieldFunctionObjects.so");
 writeControl timeStep;
 writeInterval 100;
 U U.water;
 }
