Question #682290 on Yade changed: https://answers.launchpad.net/yade/+question/682290
Jérôme Duriez proposed the following answer: It again turns out that both #1 and #2 are somewhat incorrect... (thank you Jan Stransky !) I overlooked the fact that interaction possibility depends on mask compatibility in the first place, before any avoidSelfInteractionMask consideration.. So, in an example with 3 mask values assigned to particles (0b10 = "blue", or 0b01 = "green", or 0b11 = "red"), and a with collider.avoidSelfInteractionMask = 0b01: green particles would not interact with blue particles because they are not mask-compatible (do not share any "1" bit in common) green particles would not interact with other green particles because of avoidSelfInteractionMask, red particles would not interact with themselves either, for the same reason blue particles would interact with themselves, on the contrary For the complete list of possibilities, see https://gitlab.com/yade-dev/trunk/blob/master/pkg/common/Collider.cpp#L15. It can anyway not be more confusing than my comments here... -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
