time_integration_expl

order of explicit time integration scheme in EULEREXPL setting

Default: time_integration_expl = 2
  • time_integration_expl = 1 uses for time integration the explicit Euler method, which is of first order accuracy.
  • time_integration_expl = 2 uses for time integration the explicit Heun method, which is of second order accuracy.
This influences only the approximation of the transport terms in EULEREXPL setting.
