CESEL

CESEL, Type, --,--, VMIN, VMAX, VINC
Selects constraint equations via predefined reference numbers.

PREP7: Constraint Equations

Type

Label identifying the type of select:

S	—	Select a new set (default).
A	—	Select an additional set and add it to the current set.
U	—	Unselect a set from the current set.
ALL	—	Restore the full set.
NONE	—	Unselect the full set.
INVE	—	Invert the current set (selected becomes unselected and vice versa).
STAT	—	Display the current select status.

--, --

Unused fields.

The following fields are used only with Type = S, A, or U:

VMIN: Minimum value of constraint equation reference number range.
VMAX: Maximum value of constraint equation reference number range. VMAX defaults to VMIN.
VINC: Value increment within the specified range. Defaults to 1.

Command Default

All constraint equations are selected.

Notes

The CESEL command selects sets of constraint equations (CE) via specified reference numbers. VMIN, VMAX, and VINC must be positive integer values.

For example, the following command selects a new set of constraint equations based on reference numbers 1 through 7:

CESEL,S,,,1,7,1

Data are flagged as selected and unselected; no data are actually deleted from the database.

Use CELIST to list constraint equations and their reference numbers. If a constraint equation is selected but involves unselected nodes, that constraint equation will not be listed by the CELIST command, and the solver ignores it.

Internal constraint equations are not affected by this command.

This command is also valid in POST1.
