Hey guys, I am trying to simulate a falling sphere in a water tank using overset grids (overPimpleDyMFoam).

I am able to create the overset mesh and then merge it with the background (looks OK in ParaFOAM) but I noticed 2 strange issues:

1) When merging, if I create the dummy oversetPatch in the background mesh (to force overset to be the first patch in the boundary file as recommended), it does not merge with the oversetPatch created in the first mesh, and rather creates a new patch... Not sure why this happens

2) when trying to run it states there is an issue with boundary condition files (e.g. p) where the overset type patch is expecting some value (although I have ran cases in the past and from tutorials these should just be set as type overset with nothing else).

I must be making some stupid mistake... thanks in advance for your help!
