Re: [Yade-users] [Question #439709]: Compilation problematic. Provide generic binaries please.
Question #439709 on Yade changed: https://answers.launchpad.net/yade/+question/439709 Status: Open => Answered Anton Gladky proposed the following answer: Yade-binaries with statically linked libraries are not possible, because one need to compile statically all dependent libs, which is a nightmare. Now there is a good trend in distros to drop all static binaries and it makes sense. Volunteers for creating RPM-packages are always welcome.

Thanks for the reply Jan,
I was able to get the output I needed otherwise. However, I did go back
and created a MWE to replicate the issue. My problem seems to stem from
loading a saved simulation. The MWE below replicates it after saving
then reloading a self-contained simulation.
from yade import pack,export
### DEFINING SCENE ###
O.materials.append(FrictMat(young=15e6,
poisson=0.4,
frictionAngle=radians(20),
density=2600,

O.materials.append(FrictMat(young=15e6,
poisson=0.4,
frictionAngle=0,
density=0,
label='walls'))

mn,mx=Vector3(0,0,0),Vector3(10,10,10)
sp.makeCloud(minCorner=mn,maxCorner=mx,rRelFuzz=.2,num=600)
walls=aabbWalls([mn,mx],thickness=0,oversizeFactor=2.0,material='walls')
wallIds=O.bodies.append(walls)
sp.toSimulation(material='spheres')

[Yade-users] [Question #439162]: KeyError: "Unknown energy name 'kineticParticle'
New question #439162 on Yade: https://answers.launchpad.net/yade/+question/439162 Hello yade users ! I implement some equations in the "NewtonIntegrator.cpp" script to calculate the dissipated energy by damping and the kinetic energy. The label chosen for the kinetic energy is 'kineticParticle' and for the energy dissipated by damping is 'nonviscDampParticle'. In fact, i simulate the triaxial compression test to calculate the different energy components but i obtain this error message: KeyError: "Unknown energy name 'kineticParticle'." and "Unknown energy name 'nonviscDampParticle'." I don't understand why the code don't recognize these energy label knowing that the code is compiled with the new energetic equation. you find in these links "NewtonIntegrator.cpp", "NewtonIntegrator.hpp" and the triaxial compression test script. NewtonIntegrator.cpp https://filex.univ-lorraine.fr/get?k=gJTd8XcTqX7aCgyVxJN line 55 and line 90 NewtonIntegrator.hpp https://filex.univ-lorraine.fr/get?k=RkWOFG2bi1gkbV9RXFh triaxial compression test https://filex.univ-lorraine.fr/get?k=ul6w12Hvz8wkZCE03Tl the sample https://filex.univ-lorraine.fr/get?k=xTbw7ocfTIuDoaIScZJ Best regards.
