Hello everyone! I have a wind turbine gearbox model developed as a MATLAB script. The dynamic model is complicated with 30 degrees of freedom. My question is, what is the best way to include this model in Simulink?
I have found following solutions:
  1. To develop gearbox model with blocks in Simulink;
  2. To use level-2 s-function to include code into the Simulink.
How do you think which way is better? Maybe there is another solution, which i do not know about? For me the second option is more preferable, but I am not sure how to realize it. The first option is easy to implement if we do not have that many degrees of freedom, but in my case it is to difficalt. Any suggestions highly appreciated. Thank you!

If the model has already been developed in MATLAB, you could use the MATLAB Function block
