Can somebody elaborate on this from the reference manual pg (794) :
"Wall boundary conditions for turbulent fluid flow. For the k-ε turbulence model, this condition is of the type k − r( ε ), −n · ∇ε, where r is a given function. Bidirectional constraints for the first relation imply that the second relation cannot hold."
It appears in the section of symmetric and non-symmetric constraints.
Further i have the following message printed on my log screen :
“Inconsistent point-wise unidirectional constraints found.
78 constraints are merged/removed.
More inconsistent point-wise unidirectional constraints found...”
I think, since I'm solving heat transfer with turbulent flow, the constraint by nature bidirectional.
