Surface stress load
Use the Surface stress load tool to add surface stress load to the model.
When you select the Surface stress load tool from the panel, a new tool palette opens.
Main tools on the tool palette
| Description | |
|---|---|
 | Use Define tool to add a new surface stress load to the model. |
 | Use Properties tool to check properties of existing surface stress loads. This will open the Default settings dialogue for the selected load(s). |
 | Use Hole tool to cut holes into existing loads. |
 | Use Variable intensity tool to change any existing surface load into a linear variable load by defining 3 intensity points. |
 | Use n1 numeric field to enter the value for the force. For non-variable load, this is the main constant value. For Variable intensity load, this is the value at the first intensity point. |
 | Use n2 numeric field to enter the value for the force at the second intensity point. Only available when defining Variable intensity load. |
 | Use n3 numeric field to enter the value for the force at the third intensity point. Only available when defining Variable intensity load. |
 | Use m1 numeric field to enter the value for the moment. For non-variable load, this is the main constant value. For Variable intensity load, this is the value at the first intensity point. |
 | Use m2 numeric field to enter the value for the moment at the second intensity point. Only available when defining Variable intensity load. |
 | Use m3 numeric field to enter the value for the moment at the third intensity point. Only available when defining Variable intensity load. |
 or  | Click on the down arrow button next to a numeric field to activate or deactivate the automatic numeric field filling function. When the function is active, program will automatically fill the next numeric field with the same value, while you enter a value in the current field. Active function's arrow background is marked with light color. Inactive function's arrow background is marked with dark color. Function is active by default. |
 | Use Default settings tool to change some settings (read below in more detail). |
tip
Automatic numeric field filling function does not prevent you from manually entering a different value in the automatically filled field. It is just a helping function to fill in the values faster.
Direction tools
| Description | |
|---|---|
 | Use Predefined direction function to select the load direction from 6 possible options. |
 | Use Parallel with line function to set the load direction by drawing a line in the model space. |
 | Use Perpendicular to plane tool to set the load direction to be perpendicular to a selected plane. You can select the plane in the model space. |
 | Use Object's local system tool to select the load direction from 2 possible options. |
 | Only while Predefined direction tool is selected, use this Direction tool to select one of the 6 possible options - global coordinate system X, Y or Z axis or user coordinate system x, y or z axis. |
 | Only while Object's local system tool is selected, use this Direction tool to select one of the 2 possible options - direction parallel to local x' or y' axis. |
Contour tools
For defining load and hole contours. Only available for the Predefined direction, Parallel with line or Perpendicular to plane directions.
| Description | |
|---|---|
 | Use Rectangular function to define a rectangle by two opposing corner points. |
 | Use Circular function to define a circle by center point and radius. |
 | Use Polygonal function to define the polygon with multiple consecutive points. |
 | Use Pick lines function to define the shape by using any existing closed shape that is made of lines, edges, axis or edges of a Region. |
 | Use Pick existing region function to define shape by selecting an existing Region. |
Default settings
The Default settings tool opens a new dialogue window.
- n1 - change the value of the force. For non-variable load, this is the main constant value. For Variable intensity load, this is the value at the first intensity point.
- n2 - change the value of the force at the second intensity point. Only available when defining Variable intensity load.
- n3 - change the value of the force at the third intensity point. Only available when defining Variable intensity load.
- m1 - change the value of the moment. For non-variable load, this is the main constant value. For Variable intensity load, this is the value at the first intensity point.
- m2 - change the value of the moment at the second intensity point. Only available when defining Variable intensity load.
- m3 - change the value of the moment at the third intensity point. Only available when defining Variable intensity load.
- Load case - select a load case for the load
- Comment - add a comment to the load
