Hi guys,

In kEpsilon.C and kEpsilon.H. we can find kEpsilon::R() return the Reynolds stress tensor. but in K and Epsilon equation, we dont use this function:"kEpsilon::R()". in the solver, it is not be called either. so can I just delete it?

In running case, you can in in principle delete it indeed. I suppose it is there for consistency, completeness and the possibility for future implementations. E.g, the utility "R" uses exactly the definition over there to calculate and write the Reynolds stresses. I think all RANS models have a function to return the Reynolds stress.
