How to compile a simscape model (to dll) with tunable parameters?
6 views (last 30 days)
I have a problem in simscape compiling. I need to "tune" some parameters from an external source (I already do this with a compiled simulink model) hence, with simscape I have to set them as "run-time parameters".
In this way setting the target to ert ( create visual studio solution) I am able to compile an exe file which gives me the same output of the simscape model.
Anyway my final goal is to create a DLL file that can be imported into an external software (OrcaFlex). But when I compile the project (adding a wrapper), OrcaFlex gives me the error "floating point division by zero".
If I compile the model without run-time parameters it works.
Anyone can help me?
Thanks in advance,

Try this: make the parameter you want to tune in the generated code a "Simulink variable", i.e. a variable in the Simulink model's workspace, not the MATLAB workspace. Then keep it run-time parameter. I believe this way it will appear as an input in the generated code/functions.
Here are some Doc page talking about workspace and tunability in the generated code:
