Re: [Question #244498]: matchmaker
Question #244498 on Yade changed:
https://answers.launchpad.net/yade/+question/244498
Klaus Thoeni proposed the following answer:
Hi,
you have 3 materials but you are only defining 3 matches. In the most general case 3 materials have 6 matches, for your case it would be:
(rainId,rainId), (rainId,soilId), (rainId,wallId),
(soilId,soilId), (soilId,wallId),
(wallId,wallId)
You can eliminate a case if you are sure no contact between the two
materials will occur.
As I mentioned in my previous post the error tells you that the Ip2
functor can't find a match for a contact of material 2 with itself.
Assuming wallId=2 tells you that match for (wallId,wallId) is missing
and that's the case.
