Implementation of Robin BC by groovyBC : difference wrt. theoretic solution
Hello everyone, we consider the following stationary heat equation:
At x=0 : T(0)=T0=273 K
At x=L : kT'(x)=h*(T(L)-Tinf) with k=237 W/mK, h=-100 W/m^2K, Tinf=873 K
We have implemented this BC using swak4Foam, in 0/T for the patch outlet:
However, the OF solution differs a little from the theoretic solution :
After we changed the gradient scheme to leastSquares, everything is fine !! However we still don't know why...
