Definitions

Field Contents SI Unit Example
EID Unique element identification number.

No default (Integer > 0)

PID PFAST entry identification number.

Default = EID (Integer > 0)

CTYPE Connection type between the patches. Either format connects up to 3 x 3 elements per patch (possibly more for triangular elements).
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.
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, PIDAPIDB)

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

(Integer > 0, SHIDASHIDB)

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

(Integer > 0)

GA, GB Grid identification numbers of piercing points on surface A and surface B, respectively. 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.
