groovyBC with chtMultiRegionFoam
 

Hello people,


I know the usage of groovyBC in terms of using scalar or vector fields of other patches within the simulation domain.


But I have the case that I want to use a scalar field from another region. For example I want to set a wall boundary condition of SOLID1 with the average temperature of another wall in region SOLID2 (The walls are not connected!). Does anyone know such function? I can't find anything about this kind of usage.


Or does someone know another solution for that problem beyond groovyBC ?

In response to this question, I found a resource that talks about how to do what you want:

https://openfoamwiki.net/images/1/1e...dSwak4Foam.pdf

It says do this:
varName{parserType’name/regionName}=expression;

So you would do something like this
Treg2{patch'name-of-patch/region2}=sum(T*area())/sum(area());
