groups group# [, [begin : end | group#], ...]
groups begin : end [, [begin : end | group#], ...]
An integer representing a group identifier.
An integer number representing the beginning of a range.
An integer number representing the end of a range.
Flag indicating that all groups should be active.
The groups command takes a comma-separated list of group numbers and/or begin-end pairs, and makes those groups active. Only data from active groups will be plotted.
A group is a collection of blocks belonging to the same multimesh. The existence of a group can hide the details of its decomposition into blocks. For example, blocks within a group of structured meshes are usually logically connected and can be accessed using coherent logical indices. Separate groups are usually not connected in an orderly fashion and must be accessed in different ways.
Successive groups commands are not cumulative, so each subsequent groups command turns off currently activated groups and turns on the ones that have just been specified.
If both a groups command and a blocks command have been specified, only those blocks which are in the intersection of the two sets will be selected.
groups 2,5:7 # Activate 2,5,6, and 7
groups 4 # Activate just group 4
