[Other] Dynamic Mesh problem

Kimmy · March 12, 2018, 06:39

Hello everyone, I have a question.

I'm doing a fluid simulation that describes the opening moment of the pneumatic valve.Because the geometry near the valve changes greatly and has directionality, I think movingConeTopoFvMesh is very suitable.
In fact, my process is to use FreeCAD to create the model, then use SnappyHexMesh to create the static mesh, and finally dynamic mesh.
I don't know if my idea is correct.
If anyone has a movingConeTopoFvMesh related study, please send it to me. I did not find it in Tutorials

Thank you all.

There are various tutorials for moving cones -- here is one using pimpleDyMFoam. It should be a good place to start. https://github.com/OpenFOAM/OpenFOAM...oam/movingCone
