mesh_module cutting

Purpose

Command for cutting fibers with a mesh.

Syntax

mesh_module cutting id module-ID keywords values

  • id = obligatory keyword

  • module-ID = user-defined name for the mesh module

  • zero or more keyword/value pairs may be appended

  • cutting_keyword = v_cut_thresh

v_cut_thresh value = vthresh
  vthresh = threshold relative velocity magnitude above which cutting will occur

Examples

mesh_module cutting id my_cutting v_cut_thresh 0.1

Description

This mesh module turns a surface mesh into a blade and cuts a fiber apart if a defined threshold for the relative velocity magnitude between fiber and mesh is superseded. The fiber has to be defined via cohesion fiber. This is currently the only model to work with this functionality. Please note that a fiber segment is seen as the connection between two points, and the cut is performed if the projection on the contact point is in a specific fiber segment.

Restrictions

None

Default

v_cut_thresh = 0.0
