Convergence Monitoring
Hi All,
With iterative time advancement I can watch convergence of a flow property (e.g. velocity) at a point on a periteration basis. Does anyone know how to do this with noniterative time advancement (NITA)? I only seem to be able to get a report of the residual after each time step and have no idea what it is doing within the time step itself. Cheers, Jim.

With the NITA schemes with either FractionalStep or PISO scheme, there's no need for the inner iterations (velocitypressure), hence the name NITA.That's why FLUENT report the resiudals only after each timestep. Yet the NITA schemes preserve the secondorder accuracy. The only iterations being done behind the scene are for the individual linearized equations and for the coupled (and nonlinear)momentum equations.
