Handling Study with Several Study Steps
Some studies requires that you have to run several study steps in sequence. As cosimulation only support one study step to export your model you will need to split the study in order to isolate the supported study step for cosimulation. Note that this approach only works when each study steps are run the one after the other and when the study step to run in cosimulation is the last study step in the sequence. In the case the study contains a sweep study step, this has to be disable from the study.
The steps below describes the procedure to follow:
1
In the Study you want to run in cosimulation, right-click the Time Dependent or Stationary study step and select Copy. This way you will be able to paste the study step in a separate study using the exact same settings. This Time Dependent or Stationary study step will run alone and so available for cosimulation.
2
Now right-click again the same study step and select Disable.
3
Run the study.
4
Add an empty study to the model.
5
Right-click the empty study node and select paste. You now have only the study step to run in cosimulation in the new study.
6
In the study step, expand the section Values of Dependent Variables.
7
Under Initial values of variables solved for in the Settings list select User controlled.
8
In the Method list select Solution.
9
In the Study list select the study from which you have copied the study step.
10
Under Values of variables not solved for, in the Settings list select User controlled.
11
In the Method list select Solution.
12
In the Study list select the study from which you have copied the study step.
13
Run the study.
14
You can now select the newly generated study in the Cosimulation for Simulink node.
