walberla::mesa_pd::kernel::InitContactsForHCSITS Class Reference

Detailed Description

Init the datastructures for a contact for later use of the HCSITS-Solver.

Call this kernel on all contacts that you want to treat with HCSITS before performing any relaxation timesteps. Use setErp() to set the error reduction parameter, which defines the share of the overlap that is resolved in one step (0 meaning after the relaxation the overlap is the same, 1 meaning the particles will have no overlap after relaxation). Use setFriction(a,b, cof) to define the coefficient of friction cof between materials a and b. It is assumed to be symmetric w.r.t. the materials.
