The “Analysis Tools” chapter in the PLECS manual has application examples both for PLECS Standalone and PLECS Blockset.
Open the online manual by choosing the menu “Help > PLECS Documentation”.In the frame on the left hand side click on the tab “Contents”. (If the frame is hidden, click on the tool button with the magnifying glass.)Navigate to “PLECS Online Help > Analysis Tools” and choose “Usage in PLECS Standalone” or “Usage in PLECS Blockset”, then scroll down to the section “Application Example”.If this does not help, you might consider editing your question to clarify what exactly you do not understand. Often it also helps to attach a model to show what you have.
