The
Load Definition section varies depending on the
Type selected on the
Load form. It has three sub-sections:
Direction,
Coordinate System and
Magnitude. The following examples illustrate some of the load types.
Direction:
- If
Type is
Force, the load can be defined by specifying the direction and the vector
Components or total value of the force (Magnitude).
- Load direction can also be specified by selecting an edge/sketch from the Graphics area, when the
Geometric Entity option is selected. The direction of load is the tangent vector at the start of the selected edge/sketch curve.
- You can select the following methods:
-
Components
(default)
-
Normal to Surface
-
Geometric Entity
- If
Type is
Pressure, select a face and input a value in the
Magnitude box to apply the pressure load when the
Direction is
Normal To Surface (default). It also supports
Components and
Geometric Entity.
- You can select the following methods:
-
Normal To Surface
(default)
-
Components
-
Geometric Entity
- If
Type is
Gravity, a body load can be specified by entering the acceleration value in the appropriate direction. It supports the following
Direction options:
Components, and
Geometric Entity.
- If
Type is
Rotational Force, the
Geometric Entity option allows you to use a defined geometric axis.
- If
Type is
Heat Generation,
Temperature or
Initial Conditions, a body load can be specified by entering the
Magnitude value.
Coordinate System:
- You can select the
Global and
User defined coordinate system and
Elemental coordinates when
Distributed Load type is selected.
When
Elemental coordinates are selected, the
Magnitude directions are changed as
FXE,
FYE and
FZE in case of
Force and as
MXE,
MYE and
MZE in case of
Moment.
Similar to
Constraints, you can either drag-and-drop the
Load or right-click and choose
Subcase - Edit and highlight it to include it in the
Analysis.
Similar to
Forces, you can use
Geometric Entity to use geometry to define a load direction.
The symbols of the
Load show a convenient representation of the resultant force vector.
