Parmec spring contact¶
Parmec includes a simple spring contact modeling capability, where a contact plane on one particle can be paired up with a contact point on another particle. Both particles can be analytical (need no geometry), while the contact spring and dashpot curves are user defined. Friction, including sticking and slip, can also be added. An example test of this capability is tests/spring_contact_plane.py. Parmec SPRING command is used to define the entire contact interactions (parameters spring, dashpot and friction). Upon running it generates time history figures tests/spring_contact_plane_{z,f_ff}.png and output files viewable with ParaView. An animation and the figures are included below. (…)
