UCON

The UCON command redefines and/or lists the parameters for a UCON statement.

Format

UCON/id [,FUNCTION=USER(r1[,...,r30)[/]] [,LIST]
 
[ ] Optionally select the item

Arguments

 
FUNCTION=USER(r1[,...,r30])
Respecifies and passes up to thirty constants to the UCOSUB user-written subroutine. These can be part identifiers, variable codes, and other data that the UCOSUB user-written subroutine needs to define the constraint. If the FUNCTION argument is used, it must be either the last argument in the UCON command or be followed by a backslash (\).
LIST
Lists the current values of the data in the UCON statement.
 
Caution:  
If you use the UCON command for a velocity-dependent constraint and then use the Adams-Bashforth and Adams-Moulton (ABAM) integrator to integrate the equations of motion, Adams Solver (FORTRAN) prevents execution. Under these circumstances, use a Backward-Differentiation-Formula (BDF) integrator to integrate the equations of motion.
