2nd order time integration

Lalala_CFD

Hi everyone,

Is 2nd order time integration sensitive to CFL Number? Does user need to set CFL < 1 if using 2nd order?

By default if type is set to transient, the time integration is second order.  If type is set to steady state, the time integration is first order.

In either case, the stability of the solution process generally is not limited by CFL.
