What Is the Velocity Solver?

Controlled by the segregated flow solver, the velocity solver controls the under-relaxation factor and algebraic multigrid parameters for the momentum equations. More specifically, it solves the discretized momentum equation to obtain the intermediate velocity field.

Properties

Under-Relaxation Factor

At each iteration, this property governs the extent to which the old solution is supplanted by the newly computed solution. The default value is 0.7. For the theoretical background, see Implicit Iteration.
