New question #290950 on Yade: https://answers.launchpad.net/yade/+question/290950
I intend to create a cloud of spheres in a box which has: - periodic boundary conditions for all vertical walls - and rigid floor & ceiling I am applying compression from the ceiling. Now, what I observe is that some particles cross the floor and ceiling (which are intended to be rigid) and seem to be in a perpetual motion without any interaction with the system The material properties I am using are as follows: For the floor and ceiling: FrictMat( young=200e9, poisson=0.3, density=8000. ,frictionAngle=radians(30) ,label='wall_mat') And for the particles: FrictMat( young=4e9,poisson=0.25,density=1346,frictionAngle=radians(30),label='sample_mat') Can I solve this problem by increasing the Young's modulus for both the materials and what values should I use here ? Also, wouldn't increasing the Young's Modulus for particles arbitrarily lead to unphysical response ? In addition, I am using O.dt=0.5*PWaveTimeStep() in my simulation. Now, increasing the Young's modulus would also reduce the required time step. -- 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 : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
