Prescribed Displacement

PROPERTY LOAD DISPLACE [load_name] [loadcase_no] part_name/ALL args

Argument Meaning

load_name FEMGEN load name.

loadcase_no FEMGEN loadcase number (links load to an ANSYS step).

part_name Any geometry containing nodes.

arg1 Displacement value.

arg2 Degree of Freedom Indicator (1,2,3,4,5,6), see also Table 7.5.

Notes:

1.

The interface will simply apply the same displacement value to all nodes attached to the specified geometry ie. it will not divide the displacement value by the number of nodes.

2.

If the part was attached to a local axis system for the constraints definition, the degree of freedom indicator of the displacement applied to this part is defined in this local axis system.

3.

Prescribed displacement and more general prescribed values can be defined with the FEMGEN command 'PROPERTY BOUNDARY PRESCRIBE', see above.

Refer to table 5.1 of Chapter 5 for the equivalence between FEMGEN degrees of freedom indicator and ANSYS structural degree of freedom labels.

Example FEMGEN Command:

PROPERTY LOAD DISPLACE LO1 1 L2 0.0476 1
