dimension command

Syntax:

dimension N

• N = 2 or 3

Examples:

dimension 2
dimension 3

Description:

Set the dimensionality of the simulation. By default SPARTA runs 3d simulations, but 2d simulations can also be run.

2d axi-symmetric models can be run by setting the dimension to 2, and defining the lower boundary in the y-dimension to axi-symmetric via the boundary command.

Restrictions:

This command must be used before the simulation box is defined by a create_box command.

Default:

dimension 3
