[Anton Gladky <gladky.anton@xxxxxxxxx>]

Dear Yade users and developers,

After almost 6 months of development I am glad to announce
the next Yade version 1.20.0. The complete changelog
you will find as always at the end of this message.

As was announced earlier, we are migrating the GUI part
to Qt5. This relase is able to be built against Qt5,
using -DUSE_QT5 option during the configureation step
of the compilation.

Please pay attention on the libqglviewer in your system.
It is important to know, which Qt version is used by
your libqglviewer in the system. On Debian/Ubuntu systems,
starting from libqglviewer_2.6.3 it is possible to install
Qt5 or Qt4 version of this library. Your Yade instance
should use the same Qt as the current libqglviewer in your system
otherwise you will get "segmentation fault" if you mix versions.

It is desirable to migrate to Qt5 as soon as possible, thus we
will be able to drop Qt4 in Yade not to support both versions.

Our next step will be to migrate to Python3.

The release tarball can be downloaded on GitHub or Launchpad.
Packages for Debian/Ubuntu are in preparation and will be available
within 24 hrs.

Thanks all for contributions!

Anton

Chao Yuan (3):
      -add getPotentialPendularSpheresPair() function.
      -set pore throat radius between two fictious cells negative in
invadeBoundary=true mode.
      add a new version of capillary law. (pushed by Caroline)

Francois Kneib (2):
      New viewer feature : display tori instead of spheres for 2D
simulations.     So if the viewer looks toward the right axis, on can
see circles instead of disks.     Modifications in
pkg/common/Gl1_Primitives.*pp     3 new parameters in Gl1_Sphere :
circleView, circleRelThickness, circleAllowedRotationAxis.     A new
condition to enable circleView. The code is based on initGlutGlList()
method for spheres.
      Add an example script for the tori DISPLAY feature.

Jan Stránský (4):
      fixed compilation warning
      added Polyhedra.setVertices function, which also updates
internal variables (shape.v=... does not)
      Added Facet.setVertices function to prevent memory leaks (see
bug 1041084, #8)

      Add missing space in error message
      Doc of sphSph attribute of plotDirections precized
      Introduction of surface tension as an attribute, and comments
about code objects related to capillary files
      Addition in doc of Omega.engines to state it is = to O.engines in python
      Removal of python O.engines reference

Raphael Maurin (9):
      getStressProfile: output format modification + add calculation
of granular temperature and kinetic stress tensor
      Law2_ScGeom_ViscElPhys_Basic: add a new formulation + check
Add a new formulation of the law when imposing in the material young,
poisson, and normal restitution coefficient.     The effective spring
constants ks and kn are evaluated "classically" with the young modulus
and the poisson's ratio.     The specificity of the formulation stands
in the fact that it is the restitution coefficient of the contact (en
= 2*en1*en2/(en1+en2)) that is imposed, and not the damping constant.
To achieve this, the damping constant of the contact is evaluated
resolving numerically the analytical expression 21 of [Schwager2007]
(with a minus sign, there is a mistake in the article) with a
Newton-Raphson algorithm (This was made by Francois Kneib). This does
not seem to affect the calculation time.     With this formulation,
there is no tangential viscous damping, and it is usually not possible
to access value of normal restitution coefficient lower than 0.1 (in
that case the numerical resolution does not converged in the maximum
15 iteration allowed in the code)     Together with the new
formulation, add a short check script to verify that the imposed
restitution coefficient is the one obtained.
      Law2_ScGeom_ViscElPhys_Basic: complete the documentation     Add
a more precise documentation of the law integrating the last commit.
  I didn't complete the formulation associated with Pournin2001
(precising en,es,tc) as I am not using it and I do not know it much.
      Fix compilation error in the documentation of
Law2_ScGeom_ViscElPhys_Basic     Error inserted in commit
d47b8574e8fcc2dc09b926404f08081f2194cfde
      Add a function in shop to evaluate average depth profiles     of
particle velocity (x,y,z components), and solid volume fraction.
      HydroForceEngine: switch averageProfile function into a method
  + modify documentation
      Tutorial examples: remove all deprecated 'utils.' and
GravityEngine in the example scripts
      Modify getDepthProfile to possibly average on spheres of
selected radius only
      HydroForceEngine: modify averageProfile function to handle
bi-disperse sample     Add evaluation of the average solid volume
fraction and drag force depth profiles considering the two particle
size (taken as input) as independent.
