surface model sphere/superquadric

Purpose

Modelling surface of superquadric and contact between superquadric and spherical particles. The command is not required by the Aspherix® natural language style.

Syntax

surface sphere/superquadric [other model_type/model_name pairs as described here ] settings keyword values

• zero or one keyword/value pair may be appended after the keyword settings (after all models are specified)

curvatureLimitFactor values = more or equal 0
gaussianCurvature values = yes or no
meanCurvature values = yes or no

Description

This model extends the surface model superquadric by modelling the contact between superquadric and spherical particles.

The command is not required by the Aspherix® natural language style, as it is invoked automatically by the commands particle_shape superquadric.

Restrictions

Requires particle_shape superquadric.

meanCurvature and gaussianCurvature cannot be simultaneously yes

Coarse-graining information:

Using coarsegraining in combination with this command might lead to statistically different dynamics and system state. To the best knowledge of the developers, the cross-influence between this command and coarse-graining is unknown.

Default

curvatureLimitFactor = 0 gaussianCurvature = ‘no’ meanCurvature = ‘no’
