Monitor the solved status of a simulation

You can monitor that your simulation and its components are solved via the Simulation Manager and Properties Inspector.

Check that a simulation is solved

See the Solution Status section of any of the AVEVA Process Simulation tabs other than the Help tab to check if the simulation currently displayed on the Canvas is solved. This feature analyzes the simulation as a whole to indicate the following, from left to right:

• The simulation's required data has been confirmed

• The simulation is properly specified

• The solution is solved

For example, the following indicates a solved simulation in which all three of these criteria are met:

While the following indicates an unsolved simulation in which none of the criteria are met:

Correct a simulation

1. Review the Simulation Manager. When a simulation is unsolved, a red badge appears next to the simulation, the main Flowsheet, and the Canvas object(s) responsible for the unsolved status. Hover the mouse pointer over the badge for details.

   The icon indicates that required data is not provided.

   The icon indicates that the simulation is unsolved because it is not properly specified.

   In the following example, the Flowsheet displays an unsolved status, indicating that the XV1 Canvas object requires user input.

   

2. Open the Mini Inspector for the responsible Canvas objects to correct the variables responsible for the status. Variables responsible for causing an unsolved status due to improper specification appear with a red background in their checkboxes. In this case, you may want to add a checkbox to Q, to DP, or possibly both. Knowing what to specify depends on your understanding of the problem that you are trying to solve.

   

   Note: The checkboxes indicate the specification status of a variable. If the checkbox is selected, the variable is user-specified. If cleared, the variable is calculated by AVEVA Process Simulation.

3. Correct the indicated items by specifying appropriate values.

4. Once you have corrected the items responsible for the unsolved status, the red badges are removed from the Simulation Manager and the Mini Inspector.

   A solved simulation displays as follows in the Simulation Manager:
