Hi,
I am trying to simulate the viscous flow through a convergent-divergent nozzle, I created a mesh with 60k cells and use bias to cluster more number of cells to capture the boundary layer. I am using k-e model with enhanced wall treatment and my wall y+ values were less than 1. My minimum orthogonal quality is very low(<.04). When viewed where the minimum orthogonal cells are, it was at the edge of the nozzle. My residuals remain constant for a larger number of iterations and are not below an acceptable range...I herewith have attached the relevant figures...Please let me know how I could solve the problem |
