The user has control over a number of parameters that influence numerical convergence.

Note: These values should only be changed by experienced users or under advisement by AFT Support. Poorly defined Solution Control settings can cause the model to converge on an incorrect solution without warning messages.

• Tolerance panel - The iterative tolerances that define convergence can be defined on this panel.

• Iterations panel - Additional iteration controls that can affect whether or not a model converges, or how quickly it will converge, can be defined here. Most settings on this panel will not affect the final result.

• Temperature Limits panel - Options to limit the temperature results in the solver when heat transfer is enabled.
