time_integration_impl_solve_v

order of implicit time integration scheme for velocity only (EULERIMPL)

Default: time_integration_impl_solve_v = 2 SDIRK2 method is only used if at least one phase (see KindOfProblem) is calculated with EULERIMPL. If in the case of EULERIMPL the BND_free condition is used for the velocity, then there may be problems with the second order time integration (SDIRK2). In this case the parameter time_integration_impl_solve_v can be used to solve the velocity with the implicit Euler time integration (first order). See also time_integration_impl. The time step size is controlled by the error tolerance TOL_v for the velocity.
