NLOC

Node where gap is to be placed. Defaults to current run starting point.

K

Spring constant value (must be positive).

DX, DY, DZ

Increment (in terms of the active coordinate system components) to determine gap ground point. Element length must not be zero. Constraints are automatically generated at the ground point.

GAP

Gap size (defaults to the element length).

ELEM

Element number to be assigned to gap (defaults to MAXEL + 1).

Notes

Defines a spring-gap constraint (gap element CONTAC52) at a given location in a piping run. Gives spring constraint resistance after a specified gap is closed. (See the RUN command description in Part II: Archived Commands.)
