I am working on a project where I have to design the tractor loader in simscape and understande soil tool interaction. Is it possible to couple EDEM with Simscape ?

@Steve Miller Can you please help me here?

@KANGKAN - we have customers who use Simscape and EDEM in cosimulation. It requires writing an S-Function in C code that uses the Simulink APIs and the EDEM APIs (Application Programming Interface). While it can be done many ways, the most common method is to

measure the position and velocity from Simscape
pass that to EDEM so it can move the parts colliding with the soil
within EDEM, measure the forces and torques of the soil on the part
pass those forces and torques back to Simulink so they can be applied to the part

This interface requires a very small time step.

We have an example on the File Exchange that shows coupling with discrete element modeling (DEM) software.
