Hi
I was trying to solve a 2d axisymmetric jet case using 3 blocks. I had some difficulties with that. So, i am trying to solve a simple 2d axisymmetric case. The problem is that there seems to be some cross flow across the wedge faces, when the boundary conditions seems to be even on both the faces.
Whenever i use patchIntegrate phi front or back to calculate the mass flux, it gives me a finite value. Can anybody help me. I am producing my blockmeshDict file below
