dimension species-ID value
dimension Ca 3 dimension receptor* 2
Set the dimensionality for one or more particle species. A value of 3 means the particles diffuse volumetrically. A value of 2 means the particles diffuse on a surface; see the region or triangles command.
The species-ID can contain a single wildcard character * which will match species and alias names in the usual way. E.g. species-ID can be *, ab*, *ab, ab*cd.
The dimensionality of a species cannot be changed if particles of that species already exist.
This command can only be used for spatial simulations.

Dimension = 3 for all species.
