Status: Open => Answered Jan Stránský proposed the following answer: Hello, (1) It is a 2D simulation. > it is possible, see some previous questions related to 2d simulation: https://answers.launchpad.net/yade/+question/198183 https://answers.launchpad.net/yade/+question/215571 https://answers.launchpad.net/yade/+question/174453 > (2) The numerical idealization consists of a box formed by four > plattens and its sides are constrained by a constant force(2N/m) for > numerically generating an initial state of a granular assembly and move > horizontally. > This should be possible with https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.ThreeDTriaxialEngine or https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.TriaxialStressController but I have no personal experience, so hopefully somebody else will reply :-) > (3) The top platten is driven downward and the bottom upward at a > constant velocity to simulate uniaxial compression under a constant lateral > force. > This should be provided by previous engines > (4) The simulation may run with variations of particle size and > shape(disk or ellipse). > You can use "discs" (2D projection of spheres), but there are not ellipses/ellipsoids in Yade.

What do you mean by "controlled by time step"? > > Now, there is almost no experience for me to do this work with YADE. > So my first question is whether all the above steps can be implemented in > YADE or not, and the second one is how to start the 2D simulation in YADE. > > By "can be implemented" do you mean that they can by used directly, or actual new implementation? In fact, almost anything can be implemented ;-) I hope I hepled you a bit.
