Using radius expansion method to bulid a DEM model

Asked by Huihuang Xia

Dear developers of Yade,
I am a new user of Yade, I want to build a DEM model using many sub-spheres to fill a given irregular shape with radius expansion method, such as a sand particle. But, I cannot find even an example using this radius expansion method in Yade's tutorial. Can you give me such an example to help me improving my programming skills?
Many thanks and regards,
Huihuang Xia

Hi,

Please have a look at the triax-tutorial. The TriaxialStressController provides the option "internalCompaction", which will do what you want.

Hope it helps,

Christian
