Описание
Applies a force of a given value [N] to the selected geometry.
Применение
- There are several ways to invoke the command:
- Press the
Force Load button.
- Select the Model → Mechanical Boundary Conditions and Loads →
Force Load option from the menu.
- Press the
- The Mesh object will be hidden automatically and reveal the original model. If the Mesh object is still visible, do one of the following to hide it:
- The Analysis feature parameters dialog in the task panel has also been opened.
- Press the Add button and select one or more of either faces, edges or vertices in the 3D View to apply the force to. The selected items will appear in the list of geometrical objects.
- Optionally press the Remove button and deselect one or more of the selected items in the 3D View. The deselected items will be removed from the list of geometrical objects.
- Specify the Force value in [N].
- Optionally select a face or an edge and press the Direction button to change the force direction. In a typical case, you'll leave this field empty to apply the force in the normal direction.
- Optionally check the Reverse direction checkbox to reverse the force direction.
- Click OK to finish.
Properties
- ДанныеEnable Amplitude - introduced in 1.1: Enables the use of CalculiX's amplitude for the time variation of the force load. At a given time, magnitude of the load is multiplied by the amplitude value corresponding to that time. Linear interpolation is used between the specified values. Constant values are used outside of the specified range.
- ДанныеAmplitude Values - introduced in 1.1: Amplitude table in the following format:
time_1, amplitude_value_1 …
- Default is linear increase from 0% at t=0 to 100% at t=1:
0, 0 1, 1
Примечания
- The defined force is applied uniformly to the selected objects. For example, if you define one force load with 200 N applied to two faces having the same area, each face will be uniformly loaded with 100 N.
- This feature uses the *CLOAD card in CalculiX.
