Just tried it out and you are both right. There is almost no speedup.
Thanks,
Klaus

There will unlikely be a speedup. But you can try anyway.

It would work but it would be ugly to include WireMat.hpp in the
collider's code.
I agree but I would need a quick solution.
The the sort of quick solution that you will never commit? Then try it.
My bet is that, unfortunately, it will not give a very big speedup.
The big task of the collider

Something else I had in mined, the collider could check the material of
two bodies and if it is of type WireMat then do nothing. What do you
think?

Hi Anton,
thanks for your suggestion. Actually I had already a look at the groupMask
option. It works fine if you have groups of particle which should interact or
not, as you explain in your example. However, in my case I have three groups
of particle and I want avoid contact detection between

I think one option could be to put all particles of this group on different
groupMasks. But I have 1000s of particles in this group.
try to change groupMask after interactions are created.

Klaus, do you ask that for speedup or is it really a functionality problem?
In the later case, you could use the same idea as for setCohesionNow
(https://www.yade-dem.org/doc/yade.wrapper.html?highlight=setcohesionnow#yade.wrapper.Ip2_CohFrictMat_CohFrictMat_CohFrictPhys.setCohesionNow).

Hi Bruno,
it is purely for speed up! The model already has the functionality in the IP2
functor, so creation of new interaction is omitted. However, I want to avoid
new contact detection since I am running examples with huge meshes (20
particles), and this I guess is Collider related.
And
Hi guys,
I have a tricky question. How can I avoid new contact detection between a
group of particles?
For my WireMP a first create particles which represent the net. Second, I
create a link between particle since particle interact remotely (there is no
physical contact between these
Hi Klaus,
one of possible solutions is to use groupMask', which is bitmask.
For example, you have 3 groups of particles. 1 and 2, 2 and 3 should
interact, otherwise
1 and 3 should not. In this case bitmask can be so written:
16 8 4 2 1
1) 1 0 0 1 0= 17
2) 0 1 0 1 1= 11
3) 0
12 matches
