February 10, 2020, 09:54	Overset mesh basic question - different results on background grid?	#1
courant_numero_uno New Member Join Date: Sep 2019 Posts: 17 Rep Power: 6	Hello, I am simulating flow over a static cylinder using overset mesh (overPimpleDyMFoam). The results appear different on the background grid, and it causes a difference in the solution once the flow moves past the overset patch. Do any of you have some suggestions? I am using a small time step (dt = 0.001s), and the kOmegaSST turbulence model. Using leastSquares interpolation Am I not understanding something about the overset grid? The cell size is a similar scale at the overset patch. See the attached picture for explanation:Screenshot from 2020-02-09 16-27-01.png
