walberla::mesa_pd::kernel::cnt::WallContact Class Reference

Detailed Description

Repulsive wall interaction kernel.

Implementation follows: Wittmaack, Volkov, Zhigilei, "Phase transformation as the mechanism of mechanical deformation of vertically aligned CNT arrays" - Carbon, 2019 https://doi.org/10.1016/j.carbon.2018.11.066

The force is divided into three areas. ========================== z=0, position of the wall close to wall -----------------------— z=z1+r spline interpolation -----------------------— z=z2+r far away from wall
