Hi all.
I'm trying to simulate the flow for a 3D nozzle with a domain. I have validated the same nozzle for a 2D. But now I'm facing convergence issues in 3D simulation. I have set convergence criteria of 1e-4. K and epsilon residuals are not coming down despite the number of iteration.
Quality of mesh is (Min 0.492274 Max 1)
Orthogonal Quality (Min 0.496833 Max 1)
Skew (Min 0 Max 0.672332)
Using RNG K-epsilon model

I have refined my mesh to mesh nodes of 2165700 and mesh cells of 2086714 but still I got get convergence
kindly if anybody can help me
