# GMATCH

Bulk Data Entry Defines equivalence for all degrees of freedom of grid points of two different subsets of without any requirement that these two subsets are closely located to one another.

## Definitions

Field Contents SI Unit Example
ID Identification number of the GMATCH Bulk Data Entry

No default (Integer > 0)

SETIDi Identification numbers of two SET's of GRID's to be matched. Each GRID from the first SET is matched to the closest GRID in the second SET.

No default (Integer > 0)

TOL Specifies the numeric value defining the maximum distance between two grid points to allow equivalence. All grid points in part SETID1 are considered during the search; if OptiStruct finds grid points in part SETID2 within the specified maximum distance (TOL), then such grid point pairs are equivalenced.

No default (Real > 0.0)

MOVE_FLAG (Optional) Allows you to move both grids to the same location, effectively filling the gap by stretching the elements on one or both sides. 4
