Hi,
I am trying to solve inviscid flow over circular cylinder in 2D domain (2nd order with Vekatkrishnan limiter). I have observed that solution doesn't converge when I use explicit time integration but it converges for implicit time integration. Is there any problem with explicit integration method? I am using SU2 version 3.2.3 for simulations. Please give some clarification. Thank you. |

Have you tried to reduce the CFL number? Explicit schemes require lower CFL number, on the other hand, they are less memory intensive.
