Controls
Pause Stops the solution.
Resume Resumes a stopped solution, which restarts from the last iteration.
Parameters
Flow Solver Modifies the flow solution time step and convergence criteria parameters. **Time Step (Steady State)**Modifies the initial time step with a constant value specified in the box. Convergence CriteriaModifies the initial flow convergence residual with a constant value specified in the box.
Thermal Solver Modifies the maximum allowable temperature change and convergence criteria parameters. Max Temperature ChangeModifies the initial maximum temperature change between two consecutive iterations with a constant value specified in the box. Convergence CriteriaModifies the initial convergence residual for the steady state thermal solution with a constant value specified in the box.
Update Parameters Updates the parameter values used by the solvers when you click Apply. The solvers use the new values at the next solution iteration.
