[openFoam1912] overset compare regular mesh have different results, why?
 

Dear all
I model a cylinder and plate with overset and regular mesh. it run use overPimpleFoam and pimpleFoam respectively, but the result is different. I compare the different oversetInterpolation (volumeWeight, inverseDistance, leastSquare) but it is not changes. Do you know, why this problem exist?

Thank you

Considering your mesh resolutions, I would say they look quite similar.

Hi
I change the resolution and dimensions of mesh, but the results is same. only change in oversetInterpolation may change the result, nearly.
