Available from Build 139.31800. This tab page is only visible if "SSF.On" tickbox is check on the Dynamic Tab.
User can set some criteria for the checking of Temperature, Pressure, Mass and MassFlow change in the project.
- If the project is set to run to steady state (either from the Solver Setup or Scenario type), the criteria entered on this page will be used to stop the scenario run once the conditions have been met.
- If the project is not set to run to steady state, user can still use the Solver Setting - SS Monitor page to track the worst changes.

| Steady State Finder (SSF) - Solve to Steady State | ||
| SSF... | ||
| Finder Options | ||
| On | Tickbox | Toggles the SS Finder on/off. |
| StopCount | Input | Consecutive steady steps required to stop. The number of continuous steps that the network must be steady before SysCAD will stop. |
| MaxSteps | Input | The solver will stop after MaxSteps – regardless. If this value is -1 SysCAD will keep running indefinitely. |
| TagCount | Input | The number of Tags being displayed on the page. |
| Finder Options | ||
| Step | Display | The number of steps to date. |
| SteadyCount | Display | The number of consecutive steps that the ‘Steady State’ criteria have been satisfied. |
| Finder Variables | ||

| M (Mass (Content)) ... | ||
| Test | None | Do not do any mass tests. |
| TotalMass | Apply the mass test to the total mass. | |

| Test | None | Do not do any mass flow tests. |
| TotalQMass | Apply the mass flow test to the total mass flow. | |
| Species | Apply the mass flow test to individual species flows. | |
| IndSpecies | Apply the mass flow test to a specific individual species flow. The user selects the species in the field following this one. | |
| TotalQMass/Species | Apply the mass flow test to the total mass flow and individual species flows. | |
| TotalQMass/IndSpecies | Apply the mass flow test to the total mass flow and to a specific individual species flow. The user selects the species in the field following this one. | |
| TestSpecies / TestSp | List | This is only visible if the user has chosen IndSpecies or TotalQMass/IndSpecies for Qm.Test. The user selects the individual species to be tested from a drop down list of all species in the project. |
| Rel | Input | Relative tolerance on mass flow change. |
| Abs | Input | Absolute tolerance on mass flow change. |
| Steady | Display | Only visible if Qm.Test is NOT None. The number of consecutive steps that the ‘Steady State’ mass flow criteria have been satisfied. |
