What Are Solvers?

In Simcenter STAR-CCM+, solvers control the solution and are activated once per iteration (or once per time-step for explicit unsteady simulations).

Typically, a model elects the solvers that are required. Different models can use the same solver and sometimes models need more than one solver.

Some models control other models and some only perform tasks when the solution is initialized. For this reason, not all models elect solvers. Models can also elect solvers that perform subsidiary tasks in addition to the solver that the model elected to control it.
