Question #198183 on Yade changed: https://answers.launchpad.net/yade/+question/198183 Status: Open = Answered Klaus Thoeni proposed the following answer: If you are interested in an external packing library have a look at ESys- Particle's GenGeo (https://launchpad.net/esys-particle/gengeo). You can direct import it into yade. It makes nice 2D packings. However, not sure about clumps.

The fact that the class is called Sphere doesn't mean it can't represent a disk. It is always position and radius. If you want it to be a disk, then it is a disk. A limitation is that Yade does not modelize disks in three dimensions (contact between the edge of disk A and the surface of disk B is not handled), but in 2D there is no problem. -- You received this question notification because you are a member of yade-users, which 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 #198294]: Help for porosity, apply pressure, erase, get stress
New question #198294 on Yade: https://answers.launchpad.net/yade/+question/198294 Hi, I 'm writing a code to create packing, I have some confuse, long for somebody can help to solve. 1, case one:a deep cavation of drill, how can I model the soil layer with the desired stress and porosity? whether I must use the real radius of clay ,such as 0.075mm or littler, and if I didnot use the real radius, how to give the E,v ,c, fri,density and so on? 2, what is the best way to get stress or prosity in some local volume, does predicates can do it? And how to do, is there an example? 3, when I use Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(setCohesionNow=True,setCohesionOnNewContacts=1), I have a question, whether I can use the 'setCohesionNow=false,setCohesionOnNewContacts=1' when packing with gravity and apply pressure on top of soil layer, and changes it to 'setCohesionNow=true,setCohesionOnNewContacts=0' later, is it possible to do that? 4, how to apply constant pressure on top of soil layer, and then delete some particle in a cylinder volume like drilling, can somebody give me some example, I cannot get through the documentation, whether ForceEngine() or erase() can do that, thank you! -- You received this question notification because you are a member of yade-users, which 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
