Turn off the specifications analysis while manually solving your simulation

When you are manually solving a simulation (that is, you have turned off the Auto Solve feature), you can also turn off the specifications analysis. The specifications analysis determines the number of specification changes that you need to make to keep your simulation properly specified.

Note: A simulation is properly specified when the total number of specified variables and equations equals the number of calculated variables.

Turning off the specifications analysis allows for faster performance. This feature is especially useful when you are working with large simulations and you want to make small changes, such as adding or renaming a model instance.

You should turn off the specifications analysis with caution. If you make multiple changes that can lead to a specification change, you may encounter specification errors the next time you try to solve your simulation. Specification errors are often difficult to diagnose and fix. If you decide to turn off the specifications analysis, we recommend that you periodically turn on the specifications analysis or solve your simulation to ensure that your simulation remains properly specified.

You can turn off the specification analysis only in Process mode and Fluid Flow mode, not in Dynamics mode.

Turn off the specifications analysis

1. On the Process or Fluid Flow tab, in the Solve group, ensure that the slider shows Manual.

   

2. Clear the Analyze in Manual checkbox.
