The following example uses the U2 - Steam Turbine example simulation. You can import this simulation from the %userprofile%\My Simulations\Examples folder. In this example, we modify a feed temperature in steps so that we can observe its affect on the power output of a Turbine model. After each temperature step, the software solves the simulation and captures a snapshot. See Command arguments for information on the commands used in this example.
Example: Use a scenario to set a variable value, solve the simulation, and save a snapshot
-
In the Scenario Manager, create a new scenario.
-
Edit the new scenario.
The scenario opens in the Scenario Editor.
-
In the Configuration section, select Add a command after selected row
.
A new row appears in the list of commands.
-
For the new command, do the following:
-
In the Command column, select VARIABLE.
-
In the Argument 1 column, select SET.
-
In the Argument 2 column, enter Feed1.T.
-
In the Argument 3 column, enter 500.
-
In the Argument 4 column, select K.
-
-
Select Add a command after selected row
.
A new row appears in the list of commands.
-
For the new command, in the Command column, select SOLVE.
-
Select Add a command after selected row
.
A new row appears in the list of commands.
-
For the new command, do the following:
-
In the Command column, select SNAPSHOT.
-
In the Argument 1 column, select SAVE.
-
-
Repeat steps 3-8 for each subsequent temperature step at declining intervals at which you want to solve your simulation and save a snapshot; for example, 450 K, 400 K, and so on.
Instead of repeating sets of commands with arguments that do not change for each temperature step (such as the commands for solving the simulation and saving snapshots), you can create a utility scenario that includes only those repeating commands. You can then reference and run the utility scenario from your main scenario by using the SCENARIO command and entering the name of the scenario as the first argument.
-
Select Run to sequentially perform each command in your scenario.
