Hello,
I'm struggling with a stiff case and I would like to understand better if GGI / AMI approach may be suitable.
I have an internal flow case to be run, but the inlet component has to be tested in different shapes. The mesh is static, no adaptive refinements and no movements what so ever; the only issue is the components complexity and their meshing time.
Doing multiple meshes is my last choice as the background mesh is a bit complicated and can't be defeatured; also I would prefere not to work with my standard mesher only (structured multiblock one, pretty complex) at least for the background mesh as it's pretty irregular.

Now, the inlet component has four variants but its bounding box is always the same; therefore I was wondering if is possible to use GGI or AMI (I can run both extend-41 and 1812 variants on our cluster) in order to have some sort of "plugin system", some kind of a overset-ish method...

Is this something that may work? Is GGI a technique for moving-meshes only? Does GGI requires dynamic-mesh-aware solvers even if the simulation is static and won't involve any moving part? I didn't see any reference about ggi in DyM nor standard solvers code, that's why I'm asking.

Thanks for any advice
