Applications of Dual Time Stepping to Fully Implicit Runge-Kutta Schemes for Unsteady Flow Calculations
Unsteady Flow Calculations Time Stepping
2015/6/18
Accordingly, a fast steady state solver is an essential building block for an implicit
scheme. This leads to a circular situation. We need an implicit scheme for fast
convergence to a steady state, ...
