enable_sieving_for_wall_material command

Purpose

Command for changing coarsegraining factor of particles when in contact with wall.

Syntax

enable_sieving_for_wall_material keyword value

Keywords:

Keyword	Description
material	name of the wall material
coarsegraining	new coarsegraining factor

Examples

enable_sieving_for_wall_material material steel coarsegraining 1

Description

When using coarsegraining, groups of particles are represented as larger particles to reduce computational costs. For processes such as sieving, it is important to represent the particles with their actual size when they interact with geometries. This command allows for the usage of coarsegraining in such cases by setting a local coarsegraining factor when the particles are in contact with the walls of the defined materials (e.g., coarsegraining 1 instead of 4).

Note, the coarsegraining factor specified in this command must be smaller than the one set with the coarsegraining command.

Additional information

This command can only be used when coarsegraining is active. The wall contact model must be defined before it can be applied.

Restrictions

none
