Syntax

fix ID group-ID change/size/multisphere keywords values

Examples

fix grow all change/size/multisphere mass_change_rate 0.1 region grow_reg

Description

This fix adds mass and grows particles in the fix group, to mimic the effect of mass transfer, such as spray coating. See fix change/size for a detailed description. This fix additionally implements growth in a way so that it is applicable to both spherical and multi-sphere particles. I.e., the eligible particles (containing spherical and multi-sphere particles) are tallied, and growth is applied to both spherical and multi-sphere particles. This fix also adapts the mechanical properties of the multi-sphere particles (such as inertia tensor) accordingly.

Restart, fix_modify, output, run start/stop

This fix does not need to write data to binary restart files. None of the fix_modify options are relevant to this fix. No output is stored by this fix for access by various output commands. No parameter of this fix can be used with the start/stop keywords of the run command.

Restrictions

None

Coarse-graining information:
