DynamicMesh - Move internal points
Join Date: Jan 2013

actually I am programming an y+ adaption for OpenFoam. I need a tool, which manipulates the mesh by making the thickness of the first boundary layer smaller if there is detected y+>1.
I am able to detect that vertices with toposet:
Problem: I didn't find in the web a tutorial, how to move internal points (not boundary points) of the mesh. Do anybody knows how it works?
Thanks for help,

If you look at the layeredEngineMesh code, you can see there is code that moves certain mesh points to a new position based on the calculated crank angle. You will need to do something similar, although I don't quite know how you would determine the new position.
It would have to be some kind of function that finds distance to the nearest point on a boundary patch, then takes a fraction of the distance along the vector to the nearest point on the patch and moves the new point to that position (like half the distance?). Or just a set distance along that line. There are some built in functions like that in meshTools and other libraries. Its been a while since I've had to do anything with them.
