How to get differential equations from simscape system?

Question

I have simmechanics model in simscape, I have imported it from solidworks design

I'm able to get linearized model using linmod and it is okay as any system in simulink

The problem here that I want to get the differential equations for that system, Is there any way to extract them?

[linmod](https://www.mathworks.com/help/simulink/slref/linmod.html) returns either the state-space matrices, or the numerator/denominator of the transfer function for the linearized model. Are you looking for more that? — Phil Goddard, Oct 16 '16 at 04:52
That's not possible. You'll need to resort to pen and paper to write them out, — Phil Goddard, Oct 16 '16 at 14:20

The short answer: no, there is no built-in functionality. The long answer: you'd have to parse the Simscape network, query the source equations (if the source code is visible). And stack these together. That's a pretty involved workflow.
