Mesh Morphing

FlyBob91 · December 16, 2016, 12:32

Hello Folks,
Can someone suggest me a paper/article or a case to start understanding and programming mesh morphing with OpenFOAM?

I create my own adjoint solver and i want to modify the mesh according the sensitivity i calculated. I'm working on an internal flow in a duct.

Thanks for help

Hey,

you can use the tool moveDynamicMesh, by providing a dynamicMeshDict and a pointDisplacement file with the displacementLaplacian motionSolver selected. Have a look at this site for more details:

Of course there are much more sophisticated methods than the laplacian solver, such as RBF, but this should give you a good start!
