Reply To: Convergence varying radial velocity and timestep size in a simulation

Hi John, increasing iterations per timestep will only help the solution converge better, if it isn't converging in the specified number of iterations already. As for decreasing and increasing timesteps, you also need to factor in the CFL number before doing so. CFL~1 is ideal so based on this, you can change your timestep size.
