Hi FOAMers!
I'm trying to solve a problem of heat conduction using laplacianFoam. The problem is that one of the BC is such that has convection and a heat flux of known value at the same time, according to the equation: Code:
h*(Tinf-Tb) + q/A = -K*dT/dx Another adjacent wall has only the convection part and I'm working with the next implementation with groovyBC: Code:
water { type groovyBC; variables "hwater=50.0;Twater=20.0;k=0.5;"; valueExpression "Twater"; fractionExpression "1.0/(1.0 + k/(mag(delta())*hwater))"; value uniform 50; } I would appreciate some help with the implementation of the BC explained above with groovyBC (or maybe not..) since i can't solve my problem without it. Thank you very much in advance!
