Re: Contact detection


(BTW you're probably the first person besides me to read that code.)

Hehe. I'm sure Gallizzi read it before, and I read it before you too.

 Is this contact detection method more efficient in terms of search
time than other methods based on spatial subdivisions?


It might be better in some circumstances, nobody really knows.

Keep in mind than in single thread and in a typical step with 50k element, the contact detection is 3% of the CPU time. With 5 threads, it is up to 10% (see https://yade.hmg.inpg.fr/index.php/Triaxial_Test_Parallel).

So, yes, it can be better, especially if we speak about very big simulations and massive parallelism. But currently, this algorithm works quite well with respect to overall performance.
