Moedlica and SIMULINK yield completely different results!

I'm trying to simulate a 1D model of two bodies sliding on each other with a Coulomb friction in between. I have explained the issue here in this SO post:

I would appreciate if you could help me with this.

As mentioned in the post, the time step and solver settings might not be identical for both the models. Hence this difference in outputs that you are observing.
