Hi Bruno
Why would you define a body with FrictPhys if is supposed to have a
cohesive behavior with others?
You can just give CohFrictPhys to everyone.
That's what I did so far but it is not always possible.
Any idea about the goReverse? Can it be removed?
Maybe not removed. I think it
Maybe not removed. I think it is necessary, precisely because we can
have non-symmetric functors. If you swap ids in Ip2 you may break the
work of the Ig2.
The go reverse is here for this reason (handling non-symmetric cases
without forcing a specific ordering of id1/id2 and without the need
Hi Bruno
Swapping for the Ig2 and swapping for the Ip2 are two different things.
This comment at L98 applies for geometry only.
Swapping for the Ip2 after computing the geometry would break everything
(contact normal should be inverted, etc.)
It is also what L125 suggests: assert(!swap);
Hi Klaus,
I think non-symmetric functors are rarely necessary since most
combinations can be dealt with via inheritance (e.g. Frict vs CohFrict
is interpreted as Frict vs. Frict since CohFrict inherits from Frict).
However, I am like you, I don't see the reason why it is asserted
symmetric. I
Hi Bruno

Exactly, but what if you want it to behave it like a cohesive contact. This is

Hi guys
is there I reason why we only have symmetric Ip2 functors? I recently committed
a contact law with non-symmetric Ip2 functor
(Ip2_FrictMat_FrictViscoMat_FrictViscoPhys) but at the moment it is not working
as expected. It turns out that the reason is in InteractionLoop.cpp line 122
and
