Hallo,

I am facing a problem with the c-code generation of maplesim models:

When I am trying to compile a multibody model that contains more than about 80 bodies I get an error "Error, (in GetCompiledProc) internal error: unable to find matching".

Using the code generation template it says "Error in Component cmdGenerateCode eith caption "Generate C code": (in DSN/Pantelides) internal error: unable to find matching"

Has anyone a solution to this?

Edit:

Model: Ref_Model.msim

It is a simple systems of masses connected by spring/dampers.

I am using MapleSim 7.01

The error message occurs when I try to simulate the model in maplesim, too:
