Hi all,

I want to get access from alpha field from patch1 to use it in patch2.

The problem is that my alpha field does not exist?

type     groovyBC;
variables "alphaFromPatch1{patch1}=alpha.liquid;";
valueExpression "alphaFromPatch1";

Additionally I tried with:

• alpha
• alpha1
• alpha2
• alpha.liquid
• alpha.air

But always I get an error that this variable does not exist or is of wrong type.
Does anyone have some idea?

Additionall question:

Is it possible to get velocity field U from patch1 and use it for patch2 not in an averaged value?
