COMSOL 6.4 - Grain (Dataset)

model.result().dataset(<dtag>).set(property,<value>);

model.result().dataset().create(<dtag>,"Grain") creates a grain dataset.

Table 7-55: Valid Properties for Particle Datasets.
Name	Value	Default	Description
solution	String	first available solution	The solution this dataset refers to.
pgeomspec	manual \| fromphysics	fromphysics if an applicable physics interface is available, otherwise manual	The method of specifying the particle geometry and the names of the grain position degrees of freedom.
physicsinterface	none or the tag of a valid physics interface	none or first applicable physics interface	The physics interface from which the particle geometry and the names of the grain position degrees of freedom are defined.
pgeom	String	pgeom or pgeom_ followed by the tag of a granular flow physics interface	The geometry in which the grain degrees of freedom are defined. The correct name of this particle geometry is pgeom_<tag>, where <tag> is the name for the Granular Flow interface node.
posdof	String array	Position vector components of a granular flow physics interface	The position degrees of freedom of the grains.
