Constraints Data
Hierarchy Description
The Constraint World (CONW) is a member of World. It owns Constraint Type (CONT), which is an administrative element that groups constraint data into types. Below CONT is Constraint (CONS). This element has attributes that store particular conditions to which a constraint may be subjected.
CONS owns the Case Table element (TCAS). This is a reference to a particular case for which the constraint data is applicable.
One constraint may own more than one TCAS. This could mean that the attribute of constraint is valid for more than one case (for different temperatures and pressures etc.).
If there is no TCAS, then this could mean that the attributes of CONS are valid for any particular case.
CONS has the following attributes:
TYPE
CONS
NAME
LOCK
OWNER
APPL
(application)
FORC
(applied force (load))
MOME
(applied moment)
DISP
(applied displacement)
ROTA
(applied rotation)
DLIM
(displacement limits)
RLIM
(rotation limits)
FLIM
(force limits)
MLIM
(moment limits)
DFLF
(translational flexibility factor - distance/force)
RFLF
(rotation flexibility factor)
FCOE
(friction coefficient)
CPUL
(cold pull (translational))
CPUT
(cold pull (twist))
The attribute APPL (application) is a 20-character text string; FORC, MOME, DISP, ROTA, FLIM, MLIM, DFLF, RFLF, FCOE, CPUL and CPUT are 3-element real arrays; DLIM and RLIM are 6-element real arrays.
The element CONT has an attribute RTYP (Restraint Type) which is a 12-character text string.
The element TCAS (Case Table element) has an attribute CASR (Case Reference) which references a case applicable for that constraint.
