I have a tricky question. How can I avoid new contact detection between a

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

not. So, if you see an example, the group 1 and 2, 2 and 3

The

Yes.
I could use 0 and 1 instead of False and True in the python script:
Another option is to make MatchMakers for krot and ktwist and set them to
0 so the moment will be 0. It might be an easier solution but not the
most efficient.
The best thing I can imagine is to add a MatchMaker that would not
replace includeMoment, let's call it momentMatch here.

Well I copy pasted the sudo apt-get install from the instructions. But this
did't work in my case. I got the cmake error I showed above. Nervertheless,
un-installing libopenblas-base solved the problem for me. That's whay it's not
installed ;-)

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
Sorry for late reply, but here my thoughts. I think a separation at material
level would be better, i.e. FrictMat inherits ViscElastMat which inherits
something like ViscElCapillarMat. I think it would make sense because not all
visco-elastic materials have capillar forces. What do you think?
Hi Bruno
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).
Exactly, but what if you want it to behave it like a cohesive contact. This is

Hi Anton,
are you planning to split the parameters at material level (see discussion
with Bruno)?
Thanks

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
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 guys,
is there a reason why we have two parameters here? Wouldn't one be enough?
E.i. we just use discretization and if discretization==0 than the properties
are not updated. What do you thing?

Hi Bruno,
2/ Hyperthreading is completely useless for heavy computing tasks,
actually even bad, as your results suggest.
I did some tests by enabling and disabling hyperthreading some time ago.
Conclusions: always disable hyperthreading, as you say it makes no sense for
the kind of thinks we

Wow! Speed x6 for 500k particules?!
It was definitely worth trying with larger numbers, it changes the
picture completely when the last points are included.
Very nice page.
Could you also give some absolute timings for completness? A convenient
Public bug reported:
O.reset() does not free the memory, i.e. if you run a series of
simulations in a loop the memory usage is accumulating. Here is a script

Hi Anton,
you are right, changing the script as follows has the same effect:
# -*- coding: utf-8
import subprocess
numberTests = 10
for z in range(numberTests):
