Question #686179 on Yade changed: https://answers.launchpad.net/yade/+question/686179
Status: Open => Answered Robert Caulk proposed the following answer: Hello, >Should I set distributeMass = True or False. Depends on what you want to simulate. Do you want the psd distribution applied to particle count or mass fraction? Quote from the doc[1]: "By default (with distributeMass==False), the distribution is applied to particle radii. The usual sense of “particle size distribution” is the distribution of mass fraction (rather than particle count); this can be achieved with distributeMass=True." > I wonder if all the particles are scaled up with the same scalar? If internalCompaction=True, TriaxialStressController uses growParticles [2], which changes the size of the spheres using a common multiplier [3]. > is there no particle growing during the isotropic compaction phase? Maybe they used internalCompaction=False.
