19.12. Accelerated Time Marching with the Non-Iterative Solver

When using the Non-Iterative Time Advancement (NITA) scheme, it is possible to use the accelerated time marching option for cases in which the Large Eddy Simulation (LES) turbulence model is not enabled (even though this option is intended to be used with LES). To do so, perform the following steps:

  1. Enable beta feature access (as described in Introduction).

  2. Enable the Non-Iterative Time Advancement option in the Solution Methods task page, and then enable the Accelerated Time Marching option immediately below it.
