New question #688250 on Yade: https://answers.launchpad.net/yade/+question/688250
I am trying to simulate the sand free fall. The bodies that represent the sand create them as polyhedra, add the interaction code according to the YADE guide. When the code is executed from the terminal, the creation of all the created bodies can be visualized, but when the simulation is started from the YADE window, the polyhedra disappear and in the end it seems the following warning: WARN /build/yade-fDuCoe/yade-2018.02b/pkg/common/InsertionSortCollider.cpp:242 action: verletDist is set to 0 because no spheres were found. It will result in suboptimal performances, consider setting a positive verletDist in your script. WARN /build/yade-fDuCoe/yade-2018.02b/pkg/dem/Shop_01.cpp:423 PWaveTimeStep: PWaveTimeStep has not found any suitable spherical body to calculate dt. dt is set to 1.0 This is the complete code ...

I already tried the GlobalStiffnessTimeStepper codes that suggested it in a previous post, but it didn't work. I thank you if you can help me ... -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
