I notice there is a chapter about "Structure Jacobian" in Dymola Manual 2C, but I am not sure if I could also get the "Structure Jacobian" of my own model in Dymola. I have checked the Dymola manual but didn't find how to do it.
So my question is:
There is no direct support for getting the incidence structure/structure Jacobian in Dymola 2021 and earlier.
You can some of the incidence structure of the manipulated system from the dependencies ("ModelStructure"-node) in the modelDescription.xml for FMI-export.
