Hi guys
Does anybody know what boundaryManipulate does in the kEpsilon turbulence model? (I figured out that epsilon_.boundaryField().updateCoeffs(); enforces the wall functions for epsilon, but I am unsure what boundaryManipulate does!) Quote:

Hi,
It finds the adjacent cells to the boundaries whose conditions are "epsilonWallFunction" and eliminate the corresponding equations in these cells from the matrix in order to set the epsilon values of these cells to the values calculated by the formula in the attached picture. Hope this helps, Fumiya

Does epsEqn().boundaryManipulate(epsilonm.boundaryField ()) also implies epsilonm.correctBoundaryConditions()?
My question is due to the fact that in the mixtureKEpsilon.C the correction on the boundary for epsilonm is not done, whereas boudaryManipulate is performed. Thus, maybe the former implies also the latter but I am not sure. Thanks in advance |
