User-defined fracture patterns?

[huisky]

Dear Group,

I'm going to simulate the ice fracture. Is it possible to define user-defined fracture patterns in the code?
How to do that then?
thanks very much

Check out the fracture demo in 2.79.

Usually it's a multibody system held together with constraints which break at certain tension.

To create these multibody systems you can either compose the multibody system of rigid bodies yourself, or, if you want a "realistic" shatter, you can use voronoi pre-shattering, or a multitude of other pre-shatter algorithms.

Thanks so much for your kindly reply!
I don't really need it to be really "realistic".
Could we get the contact forces as an output?
Is it possible to include the water into the simulation, so the ice fragments interactions could be computed?
