This page can be used to help with debugging the project when required. User can switch on / off various options to help narrow down the problem area.
| Tag (Long/Short) | Input/Calc | Description |
|---|---|---|
| Call Counts & Timers per Node (Displayed for Dynamic Simulation only) | ||
| NodeStats.Generate | Tickbox | (Displayed for Dynamic Simulation only) Toggles the NodeStats option on/off. If this is selected, individual unit's solver related statistical information will be display on the unit model's (e.g.: tank, pipe) access window. |
| The following are for Steady State Simulation only. | ||
| Analysis... | ||
| Requirements | ||
| Trace.On | Tickbox | By default, the Trace.On is always switched off when a project is loaded (the setting is intentionally not saved). When the user requires this feature, simply turn it on, then run the project to see the largest change in the project. |
| History.Length | Valid Range 3-20 | This effects how many columns are being displayed or reported per variable. For example, if Show.Values are on, and History.Length = 5, then these columns Val[0] - Val[4] will be shown in the Results section. |
| Collect.. | ||
| AllChanges | Tickbox | Collect all the changes (this will contain a lot of information) |
| Temperature | Tickbox | Collect temperature values |
| Pressure | Tickbox | Collect pressure values |
| Mass | Tickbox | Collect Mass values |
| PhaseFractions | Tickbox | Collect Phase fraction values |
| SolidSpecies | Tickbox | Collect solid species values |
| LiquidSpecies | Tickbox | Collect Liquid species values |
| VapourSpecies | Tickbox | Collect vapour species values |
| XRefs | Tickbox | Collect controller cross reference data |

| Solver Control | ||
| Run-Then | Continue | After solve has started, run the number of steps in Step.Count, then continue. |
| Pause | After solve has started, run the number of steps in Step.Count, then pause. | |
| Stop | After solve has started, run the number of steps in Step.Count, then stop. | |
| Step.Count | Input | User specifies how many steps the solver should complete for the analysis. Works in combination with the Run-Then selection. |
| Clear | Button | Clears the current data. |
| Run | Button | Runs the solution for a number of steps. The number of step is specified in the step.count field. |
| Idle | Button | Pauses the simulation. |
| Step | Button | Runs the simulation for one step. |
| Stop | Button | Stops the simulation. |
