surface model superquadric/orthogonal

Syntax

surface superquadric/orthogonal [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 is the surface model for smooth convex superquadric particles. It is similar to the surface model superquadric, but in contrast the overlap vector is orthogonal to surfaces of contact particles.

This model is used in the framework of superquadric simulations. For more information see also the SUPERQUADRIC guide.

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’
