Hi Foamers

I would like to use the attach detach approach to close valves in a combustion engine. It works fine without flow solver, but with flow solver it crashes.

What do I need in creating a flow solver for a mesh, which deals with topology changes? I guess I ve to update my boundary conditions at the moment when faces are added or removed, but how?

I hope this is the right forum, since it deals with meshes.

Thx in advance
Peter

Peter,
I am just starting to look at this myself. Are you using
sonicTurbDyMEngineFoam ?

Yes I have used it, but just to test the engineTopoChangerMesh class.

I am about to adapt the dieselEngineFoam solver to use the engineTopoChangerMesh class but I am struggling with the attachdetach boundary conditions and the right meshflux.
Do you have experiences with solver which uses meshmotion ?

Peter

Hi,

Unfortunately, my experience is limited to advising Sandeep Menon on building an incompressible solver with mesh motion and topo changes. It is awfully convenient having him here. I am going to be sad when he graduates.

I have just started poking around with sonicTurbDyMEngineFoam in order to try out some of our remeshing ideas. I see that much of the engine mesh coding is very application-specific.
