PROPERTY LOAD GRAVITY [load_name] [loadcase_no] ALL args

**Table 7.7:** GRAVITY load arguments.
Argument	Meaning
load_name	FEMGEN load name.
loadcase_no	FEMGEN loadcase number (links load to an ANSYS step).
ALL	Whole model.
arg1	Gravitational Constant.
arg2	Degree of Freedom Indicator (1,2,3), see also Table 7.5.

Notes:

1.: The interface program will apply the gravitational load as an acceleration vector applied to the whole model. The degree of freedom indicator defines which vector coordinate the constant applies to.
2.: The sign of the constant should be such that the direction of the gravity load displayed within FEMGEN is the chosen one. The interface program writes the acceleration vector with the correct sign in accordance with ANSYS convention.

Example FEMGEN Command:

PROPERTY LOAD GRAVITY LO1 1 ALL -9.814 3
