Gradient over interior (shadow) wall

D Krijgsman

Hi I have moddeled a 3d geometry (turbine section) with an interior wall (blade of zero thickness). So fluent nicely creates the wall and a shadow wall. Everything seems fine until I want to use mesh adaptation. Because whenever I try to addapt the mesh based on gradients, fluent calculateds the gradient accros the wall. Now fluent only wants to addapt the mesh on the wall, because there is such a gradient (which is logical, because there are different pressures on each side of the wall). Does anyone know how to fix this problem? I can of course modify the grid such that the blade has a finite thickness, but I hoped there is another solution. Kind regards Dinant
