hey, I am doing a simulation on wavy plate with a hole on it and cold air is coming from the hole, mixing with hot air and making a film on the wall. I am using steady k-e viscous model realizable enhanced wall effects. I am running its mesh with above 5 lakh elements but the problem is that for low y+ i have made spacing near the wall very fine and after doing this even at 0.1 m/s velocity input its diverging even after decreasing the relax-parameters, what should i do? I need to run it at 248 m/s for hot air at 2066k and 95m/s for cold air at 516.6k
