I am currently working on a project (modelisation a magnetic bearing with a rotor) and I have noticed that it requires about eleven hours for C-code generations that is very annoying. I tried to reduce my model in that way : now for the modelisation of my rotor I only have two continuous integrator and a gain but the C-code generation still requires 2h30... I really don't know how I could fix this problem.. :(

Approx how many blocks are in your model? Are you using basic Simulink blocks are are you using Simscape blocks?

I am using just basic blocks, in a subsystem with a mask :
It is actually a simple block.. not even high calculation in there !

It does not make sense that this model would take so long to generate code. I suggest you contact support@mathworks.com and send them your model.
