MATLAB: Simbiology parameter is not recognized by EventFcns

events ruleSimBiology

I have developed a simple simbiology model where my parameters are scoped to the model. There is an Event within the model that gives the the following error:
The left-hand side of event function does not refer to a non-constant species, parameter, or compartment object.
Any ideas on what I might be doing wrong? I attach the .sbproj file in case it is of any use.
Many thanks

  • Hi,
    It looks like the event is changing the value of a parameter that is marked as constant. You can change the "Constant" property by double clicking on the parameter in the diagram. This opens up the Block Property Editor where you can uncheck "ConstantValue". Alternatively, you can open the Table Overview (Model pane -> Open -> Table Overview) and uncheck the "Contant" checkbox for this parameter.
