Re: [Yade-users] [Question #700271]: Rotational Kinetic Energy
Question #700271 on Yade changed: https://answers.launchpad.net/yade/+question/700271 Status: Open => Answered Jan Stránský proposed the following answer: Hello, the proper answer depends on your actual use case (providing a MWE [1] would help), i.e. body shapes, no/yes clumps etc. IMO the easiest approach would be to compute total kinetic energy using predefined function and "easily" subtract linear kinetic energy. Something like: ### (not tested) tot = utils.kineticEnergy() lin = sum(0.5*b.state.mass*b.state.vel.squaredNorm() for b in O.bodies) # (!) needs a bit different code for clumps rot = tot - lin ### Another approach would be to compute it "manually" according to formula in [2] as 1/2*∑ωIω^T. Yet another approach would be to split the code of kineticEnergy to compute separately linear and rotational kinetic energy. Or ..

[Yade-users] [Question #700271]: Rotational Kinetic Energy
New question #700271 on Yade: https://answers.launchpad.net/yade/+question/700271 Hello YADE user! I am working on a simulation of periodic triaxial test which is very similiar the one from documentation. I want to evaluate of rotational kinematic energy of the particles during the test. So far I know yade._utils.kineticEnergy() is used for calculation of total kinetic energy. Is there any commend to get the rotational kinetic energy? I would be glad if you help me to find a way to calculate it. Thanks in advance. -- 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
