The Stress Scenario tab can be accessed by clicking “Stress” on the main “Scenario Setup” menu. For this case, the user has full freedom to apply loads and restraints to any face.

1. Under the Physics tab, click the drop down arrow of the Apply Physical Conditions box. This drop down menu includes all of the restraint and load options that can be applied.
2. Select at least one load and one restraint to apply to your model. Restrained faces cannot move in any direction, and serve to “anchor” the object in space.
   Important Reminder: In order to launch the simulation, at least one restraint and one load must be selected.
3. Click [Restrain selected faces]
   This will bring you back to the main screen.
   
4. Click [Add loads]
5. Select the faces on the model to apply the load to
6. Select a force type from the pull down menu and adjust settings to desired levels using the sliders. (See below for descriptions of the different force types)
   Note: The up/down arrows on the sliders can be used to get a more exact value.
   
7. Click [Done] which will return you to the “advanced scenario tab”
   Note: A preview of the load you just added should be visible
   
8. Add additional loads or press [Simulate] to run the simulation

This option places a vector force on the faces you select. A vector is a force with a magnitude and direction. The force is distributed among all the selected faces.
* To select the face to apply the vector load to, simply click on the desired face on the object itself. To select faces with more precision, check the “Select one face at a time” box.
* To change the magnitude of this force, move the slider. You can also click the up/down buttons for a more exact reading, or type in the desired magnitude.
* To change the direction of this force, move the X, Y, and Z Component sliders. You can also use the up/down buttons or text input to achieve the desired direction. For a visualization of the vector you just created, look at the coordinate system in the box at the lower right of the screen.
Note: The X, Y, and Z directions do not change–regardless of what you chose to be the “up“ direction.
* Click the [Save] button to save your changes and continue setting up your simulation.

This option applies a pressure load to the selected faces.
* To select the face to apply the vector load to, simply click on the desired face on the object itself. To select faces with more precision, check the “Select one face at a time” box.
* To change the magnitude of the pressure, use the slider, +/- buttons, or type in the desired value. Note that positive pressures push into the selected faces while negative pressures pull. Notice that the “Pressure Magnitude” slider and “Resultant Force” slider move together. This is because the two values are inherently coupled by definition: the resultant force equals the pressure times the area of application.
* Click the [Save] button to save your changes and continue setting up your simulation

The final advanced load option is gravity. Considering the mass of the model, the force due to gravity will be computed and applied to the model. No special options are available for this load case. Simply click [Add Gravity].
