PROPERTY LOAD CONV [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 Geometry containing element faces/edges.

arg1 Film coefficient value.

arg2 Bulk temperature value.

arg3 Degree of Freedom Indicator (0,1,2).

Notes:

1.

Valid part types are beams, plate edges, shell faces, brick faces.

2.

The degree of freedom indicator should be set to zero (normal) for plate and brick elements. It should be set to 1 or 2 for beams, following ANSYS convention. For shell elements, if the degree of freedom indicator is set to zero then the interface program writes it as direction 1 in ANSYS convention. If it is different from zero, its value (1 or 2) should follow ANSYS convention.

3.

The user should be warned that, as a result of note 2, when the degree of freedom indicator is not equal to zero, the load displayed in FEMGEN may not correspond to its actual definition as seen by ANSYS.

Example FEMGEN Command:
