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.

Best,
