Question #703292 on Yade changed: https://answers.launchpad.net/yade/+question/703292
Jan Stránský proposed the following answer: > I mean I only apply force in the designated area (other than gravity) and the rest of the area uses only gravity. For example, there is a 30m box, I only apply one force in the area of 0 to 15m, and all these 30m will receive the action of gravity. yes, it is possible. You simply select desired particles and apply force on them. > Also, in O.forces.setPermF(0,(1,0,0)), does 0 refer to the magnitude of the set force? (1, 0, 0) is the position of the applied force? See documentation [5,6,8]. 0 is particle ID (1,0,0) is the applied force vector > If I'm right, then it's just applying a concentrated load, Yes, force is applied to particle "center" (particle.state.pos). > not the uniform load I need. DEM is Discrete element mehod, everything is discrete. You can think of it such as nothing like uniform load exists in DEM. > Maybe I can use O.forces.setPermF(0,((1,0,0),(2,0,0)))?
