Load Definition

 

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

Argument Meaning

load_type Load type (e.g. PRESSURE).

load_name Optional load name identifier (for reference purposes).

loadcase_no Optional FEMGEN loadcase No.

part_name/ALL Geometric part to which load is applied.

args Varying arguments depending on load_type

Notes:

1.

The part name may be either a single part in the model geometry or a set of such parts. In either case the interface expands the geometry-based load definition into a series of nodal or element-wise loads.

2.

The use of ALL for the part name is only valid in circumstances where all parts of the model have a valid geometry for the load in question.

3.

The command arguments vary with the load type and are described in the following sections. For all loads types, the actual load values (be it per unit depth, area, or circumference) must be entered correctly by the user. The interface, for example, does not attempt to multiply load values by element thicknesses or areas.

4.

FEMGV 4 Load Masks, Space Curves and Local Coordinate systems are supported.

The following load types are supported:

Generic Load Type FEMGEN Load Type Application

Uniform Pressure/Moment PRESSURE Element faces.

Concentrated Force/Moment FORCE Nodes.

Prescribed Displacement DISPLACE Nodes.

Gravity GRAVITY Whole elements.

Linearly Varying Pressure/Moment HYDROSTA Element faces.
