Surface temperature variation load
Use the Surface temperature variation load tool to add surface temperature variation load to the model.
When you select the Surface temperature variation 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 temperature variation load to the model. |
 | Use Properties tool to check properties of existing surface temperature variation 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 t1 numeric field to enter the value for the top layer of the load. For non-variable load, this is the main constant value. For Variable intensity load, this is the value at the first intensity point. |
 | Use t1' numeric field to enter the value for the bottom layer of the load. For non-variable load, this is the main constant value. For Variable intensity load, this is the value at the first intensity point. |
 | Use t2 numeric field to enter the value for the top layer at the second intensity point. Only available when defining Variable intensity load. |
 | Use t2' numeric field to enter the value for the bottom layer at the second intensity point. Only available when defining Variable intensity load. |
 | Use t3 numeric field to enter the value for the top layer at the third intensity point. Only available when defining Variable intensity load. |
 | Use t3' numeric field to enter the value for the bottom layer 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
The image in the Default settings dialogue is a good reminder of what top/bottom (t1, t1', t2, t2', t3, t3') means for this load.
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.
caution
All temperatures are measured against the installation/ambient temperature and are not absolute values.
Contour tools
For defining load and hole contours.
| 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.
- t1 - change the value for the top layer of the load. For non-variable load, this is the main constant value. For Variable intensity load, this is the value at the first intensity point.
- t1' - change the value for the bottom layer of the load. For non-variable load, this is the main constant value. For Variable intensity load, this is the value at the first intensity point.
- t2 - change the value for the top layer at the second intensity point. Only available when defining Variable intensity load.
- t2' - change the value for the bottom layer at the second intensity point. Only available when defining Variable intensity load.
- t3 - change the value for the top layer at the third intensity point. Only available when defining Variable intensity load.
- t3' - change the value for the bottom layer 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
