Soil-Tool interaction

Hi Damien,

Learning a lot with the help of Granoo, works a treat !

Here is a question : is it possible to build a domain with cylindrical shapes instead of spheres ?

Cheers, Peter

N.B. A simulation with the domain split in 2 layers with different beam properties, denoted by the colours.

Yes, this is possible. You can take a look at the 00105 example.

However, be careful: collision detection between non-spherical shapes and non-convex polyhedra, such as the blue one in your animation, will not work properly. If you want to do that, you need to manually split your non-convex shape into several convex bodies.
 
Also, collisions with inner shapes (for example, if you fill a box with spheres, the box is the "inner" shape) will not work with non spherical bodies. Again, you need to split your inner shape into outer shapes or planes. To be honest, we don’t use this feature ourselves, which is why we’ve left it as it is… not very practical, but it works.

Cheers,
Damien
