Convergence too fast -- CFD Online Discussion Forums

March 28, 2017, 17:25	Convergence too fast	#1
ntzortfo New Member Join Date: Nov 2016 Posts: 3 Rep Power: 9	Hi. I'm simulating the rear spoiler of a car. My problem is that my solution converges too fast, after 150 iterations. My turbulence model is k-ω SST, double precision. Coupled scheme, second order discretization. Y+ is around 1, under-relaxation factors in default. Mesh size is around 8000000 (spoiler total length is around 650mm). Velocity residuals 10^-6, omega 10^-4, k 10^-3, continuity ~0.5*10^-3 Is it normal to converge so quick? Should I increase the mesh size in order to get a more accurate solution? Am I missing something?
