Question about parallel calculation of Yade when using Polyhedra particle.

Furthermore, there is another error:

terminate called after throwing an instance of 'CGAL::Assertion_exception'
terminate called recursively
  what(): CGAL ERROR: assertion violation!
Expr: is_finite(d)
File: /usr/include/CGAL/GMP/Gmpq_type.h
Line: 168
Aborted (core dumped)

Thanks a lot!

Hi Henry,

when having errors, always try to find the very first one. The rest might
just be the result of the first one. If I read the code correctly, you
should have got this error prior to the mentioned by you:

verletDist is set to 0 because no spheres were found. It will result in
suboptimal performances, consider setting a positive verletDist in your
script

by default, value of InsertionSortCollider.verletDist is -0.5. If the
simulation contains spherical particles, it is somehow computed from
spheres automatically. If there are no spheres, then you got the error. A
solution (not tested) is to set it manually, i.e.

O.engines = [
  ...
  InsertionSortCollider(verletDist=0.1,...),
  ...
]

Concerning the second error, what version of Yade do you use? I got the
same error some time ago, then I updated to the newer Yade git version and
the error disappeared..

cheers

Many thanks to Dr. Jan.

For the second error, I found there is an resolution method. But my OS is Ubuntu 15.04, and I can't install libqcgal-dev.

Warning

If you have Ubuntu 14.04 Trusty, you need to install libqcgal-dev from our external PPA. Otherwise the following error occurs on AMD64 architectures:

terminate called after throwing an instance of 'CGAL::Assertion_exception'
what(): CGAL ERROR: assertion violation!
Expr: -CGAL_IA_MUL(-1.1, 10.1) != CGAL_IA_MUL(1.1, 10.1)
File: /usr/include/CGAL/Interval_nt.h
Line: 209
Explanation: Wrong rounding: did you forget the -frounding-math option if you use GCC (or -fp-model strict for Intel)?
Aborted

Are you able to test yadedaily and report, whether you get the
same error there?

Yes, I use the "Yade 2015-06-15.git-f44c022 " and "Yadedaily",there are all have the same error.

Thanks a lot!

Hmm, it looks like it has nothing common with the case, mentioned in
documentation. Please provide the minimal working script and open a bug.
You can use Launchpad for that or GitHub issue tracker [1].

Hi Henry,

I am sorry for confusion and thanks for reminder. I solved the second error
exactly by adding -frounding-math to the compiler options, i.e.

cmake ... -DCMAKE_CXX_FLAGS="-frounding-math" ...

cheers

Many thanks to Dr. Jan. But there still has this error, even though I have rebuild my Yade again according your suggestion.
And only when the number polyhedra particles is larger (for example larger than 2000).
Thanks a lot!

Henry

What exactly does "rebuild" mean? Did you run make clean or deleted the
build directory? I am not sure that mere "cmake ...; make" would work..
