# PARAM, GPSLOC

Bulk Data Entry Controls where the grid point stresses are calculated for output to the .mnf file.

Parameter Values Description
GPSLOC <Z1, Z2 and MID> The highest stresses are at the bottom (Z1) or top (Z2) surface of the shell. For pure bending, they have the same magnitude.
GPSLOC is used to specify the location of the calculation of the grid point stresses. They can be calculated at:
Z1 (Default)
Bottom surface
Z2
Top surface
MID
Mid-plane
