Dynamic Mesh Diffusivity Problem
I am trying to implement a multi-element dynamic mesh (wing & flap) where both elements rotate independently (Structures.png). The latest issue is that of diffusivity in the dynamic mesh. The trailing edge of the flap is overlapping the surrounding mesh (structured - Trailing edge.png), causing errors and failure to complete any simulation (moveDynamicMesh, pimpleDyMFoam). I am confused because I use the same diffusivity (inverseDistance) that is used in tutorial wingMotion2D_pimpleDyMFoam, but in the wingMotion tutorial, the mesh surrounding the trailing edge does not perceptibly deform locally at all (attached - g.jpg).
Can anyone suggest how I might fix this diffusivity problem? I have tried changing the code of inverseDistanceDiffusivity.C line 110 from
