Examples
Add Starting Point and Highlight the Model Slice
Add a new starting point to the active Model Slicer configuration, and then highlight the model.
1. Open the sldvSliceClimateControlExample
example model.
open_system('sldvSliceClimateControlExample');
2. Create a Model Slicer configuration object for the model by using slslicer
.
obj = slslicer('sldvSliceClimateControlExample');
3. Activate the slice highlighting mode of Model Slicer to compile the model and prepare the model slice for dependency analysis.
activate(obj);
Consider turning on Fast Restart before launching Model Slicer for simulation based workflows. Do not show again.
4. Add the Out1
outport block as the starting point and highlight the model slice.
addStartingPoint(obj,'sldvSliceClimateControlExample/Out1');
highlight(obj);
The area of the model upstream of the starting point and which is active during simulation is highlighted.
5. Terminate the model highlighting mode and discard the analysis data.
terminate(obj);
