Steady Solution Control Group

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.

  • Solution Method panel - The calculation method can be defined on this panel.

  • 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.

  • Pressure and Temperature Limits panel - Options to limit the pressure and/or temperature results in the solver.
