Question #660155 on Yade changed: https://answers.launchpad.net/yade/+question/660155
Rodolfo França de Lima posted a new comment: I will try to explain it better. I am using the dragengine in YADE, so that I’m interested in the terminal velocity of the body. The terminal velocity depends on the mass, the drag coefficient and the projected area. With simple spheres, Yade calculates it right, but my problem is with clumps. I have a clump composed of some spheres, if it is falling sideways, the terminal velocity will be smaller than when falling pointing to the ground. It happens because of 2 factors, because the projected area “like the shadow”, will be smaller, and also because the drag coefficient would change. Even if I keep the same drag coefficient, the terminal velocity will be different because of the change in the projected area. When I simulate the clump in YADE, it does not happens. I suspect that it is because YADE just computes the drag force for each independent sphere, and not the clump. Is there a way to simulate the drag force at the clump level, and not just for the spheres as if they were not part of a clump? -- 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
