Re: [Yade-users] [Question #706494]: Spherical packing of binary mixtures in a cylindrical container
Question #706494 on Yade changed: https://answers.launchpad.net/yade/+question/706494 Status: Open => Answered Karol Brzezinski proposed the following answer: Hi Soheil, I recommend using the makeCloud() [1] method which allows you to create packing with a prescribed size distribution (see the example [2[). Please note to set distributeMass=True in your case. This method creates loose packing, so you need to create 'higher' packing, and allow the particles to fall under gravity.

Karol Brzezinski proposed the following answer:
Hi,
MWE would be appreciated [1].
Using the' calculator filter', you can always compute anything in
ParaView from matrix components.
Load the VTK file, and then use the calculator filter. You can type the
formula:
"Strain_matrix_0"+"Strain_matrix_4"+"Strain_matrix_8"
or select other components using the "Scalar" button. Next, you can
visualize the 'Result'.
The MWE that I used to generate the file is as follows:
centers = []
for x in range(2):
for y in range(2):
for z in range(2):
centers.append((x,y,z))
O.bodies.append([
sphere(center=center,radius=1,) for center in centers
])
sp = SpherePack()
sp.fromSimulation()
TW=TesselationWrapper()
TW.triangulate()
TW.computeVolumes()
TW.setState(0)
shiftBodies([4,5,6,7],(1,0,0)) # move spheres without engines (I am just being
lazy)
shiftBodies([2,3,6,7],(0,1,0))
shiftBodies([1,3,5,7],(0,0,1))
TW.setState(1)
TW.defToVtk("strain.vtk")
###
Cheers,
Karol

[Yade-users] [Question #706506]: How to output volumetric strain (micro strain field) in vtk file
New question #706506 on Yade: https://answers.launchpad.net/yade/+question/706506 Hi, Referring to [1], we can use defToVtkFromPositions() to write a vtk file to visualise the deviatoric strain filed in paraview. For example: defToVtkFromPositions(position1.txt,position2.txt,"output_deviatoricStrain.vtk"). In this vtk file, it can show: solid color, strain_deviator and strain_matrix. It seems that no volumetric strain field from this vtk file. I would like to ask how to write a vtk file to visualise the volumetric strain field. Thanks.
