Field

Contents

EID

Unique element identification number.

No default (Integer > 0)

PID

PFAST entry identification number.

Default = EID (Integer > 0)

CTYPE

The type of connection between the patches. Either format connects up to 3 x 3 elements per patch (possibly more for triangular elements).

For PROP, the connection of surface patch to surface patch is defined by specifying the property numbers of shells on side A and B, PIDA and PIDB, respectively.

For ELEM, the connection of surface patch to surface patch is defined by specifying IDs of shells SHIDA and SHIDB, respectively.

No default

PIDA, PIDB

Property identification numbers of PSHELL entries defining surface A and B, respectively. Required when CTYPE = PROP.

(Integer > 0, PIDA ≠ PIDB)

SHIDA, SHIDB

Element identification numbers of shells defining fastener ends A and B, respectively. Required when CTYPE = ELEM.

(Integer > 0, SHIDA ≠ SHIDB)

GS

Identification number of a grid point which defines the location of the connector. See comment 2.

(Integer > 0)

GA, GB

Grid identification numbers of piercing points on surface A and surface B, respectively. See comment 3.

(Integer > 0)

XS, YS, ZS

Coordinates of point that defines the location of the fastener in the basic coordinate system. It is an alternative way of specifying the location of GS.
