In the OP there is some description, but it is too vague. E.g. "fall down", but without context and with your statement that you blocked DOFs and set zero velocity it does not make sense.. Although, with a MWE, it would be different and probably a good description..

I use checkUnbalanced() to check the balance of the particles, before this string of code, I have set up some particles (you can call it the first part of the code), qiyong() is the function I use to generate the second part of the particles, in the checkUnbalanced() function, after some conditions are met, qiyong() will be called, which will generate the second part of the particles. But when generating the second part of the particles, some particles will intersect with the first part of the particles and cause the subsequent simulations to not run as I expected, how do I solve it? -- 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 : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp

[Yade-users] [Question #701936]: Why do particles intersect?
New question #701936 on Yade: https://answers.launchpad.net/yade/+question/701936 I want to add some other particles using O.bodies.append() on the basis of having some particles (which we call it with the first part of the particles), we call it with the second part of the particles, and I use b.state.vel = (0,0,0) b.state.angVel = (0,0,0) fixes the first part of the particles, but I found that some of the particles of the first part fall down and intersect with the particles of the second part, why is this? -- 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 : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
