-There are six quick scenarios available in Intact.Design. Programmed loads and restraints are placed on the object depending on which scenario you select. There are a few options you can change, but Intact.Design does most of the work for you! +There are six quick scenarios available in Intact.Design. Programmed loads and restraints are placed on the object depending on which scenario you select. There are a few options you can change, but Intact.Design does most of the work for you! For more advanced setup, check out the **[[http://www.intact-solutions.com/learning/doku.php?id=wiki:id:advanced_scenario|stress scenario]]** page.  For vibration and frequency analysis, see the **[[http://www.intact-solutions.com/learning/doku.php?id=wiki:id:vibration_scenario|vibration scenario]]** page. 
  
 =====Gravity===== =====Gravity=====
 **Intro:** The acceleration due to gravity is approximately 9.81 m/s/s or about 32.2 ft/s/s. A force is defined to be a mass times an acceleration. The acceleration is defined to be gravity and the mass is calculated from the density of the material and the volume of the part. Any object made must be able to withstand at least this amount of force. Issues tend to arise in larger, more complex structures, due to the weight and loads the supports take.\\ **Intro:** The acceleration due to gravity is approximately 9.81 m/s/s or about 32.2 ft/s/s.

-**Controls:** To setup a gravity simulation, the user must specify the "up" direction and the material. Once the material is chosen, the density and part volume defines the mass, which in turn defines the force due to gravity.  The force of gravity is always applied in the “down” direction. Additionally, the computer automatically restrains the “bottom” faces.\\+**Controls:** To setup a gravity simulation, the user must specify the "up" direction and the material.

 **Usefulness:** Often structures will be most affected by gravity. Things like bridges and buildings will contain other loads from people and vehicles, however, the most significant forces will be due to gravity. **Usefulness:** Often structures will be most affected by gravity.

 =====Bend===== =====Bend=====
 **Intro:** This scenario applies equal torques to opposite sides of the model. This causes the model to either elongate or bend, depending on the application.\\ **Intro:** This scenario applies equal torques to opposite sides of the model. This causes the model to either elongate or bend, depending on the application.\\
-**Controls:** First, specify the "up" direction, which will define the axis around which the torque is applied.  Use the slider to adjust torque magnitude.  The "switch orientation" button changes the direction of applied torque by 90 degrees. The restraints are applied to several of the faces near the centerline of the object (as defined by the two faces the torques are applied to). Intact does this automatically, and cannot be changed by the user. To apply more specific loads and restraints, see our **[[http://www.intact-solutions.com/learning/doku.php?id=wiki:id:advanced_scenario|stress scenario guide]]** +**Controls:** First, specify the "up" direction, which will define the axis around which the torque is applied.  Use the slider to adjust torque magnitude.  Switching the sign (+/-) of the magnitude changes the torque from clockwise to counterclockwise, or vice versa. The "switch orientation" button changes the direction of applied torque by 90 degrees.

- For the restraints, the program chooses several of the faces near the centerline (as defined by the two faces the torques are applied to). This is done automatically, so there is no way to change the orientation of the constraints with respect to the loads.\\+
 **Usefulness:** Bending occurs in many straight, long members like trusses on a bridge. In any situation where a load is not symmetrically distributed or if the restraints aren’t symmetric, there will be a torque caused, and it may be possible to use this scenario. **Usefulness:** Bending occurs in many straight, long members like trusses on a bridge.

In this case, the bottom plane is restrained while a torque is applied to the top surface of the model. \\ 
-**Controls:** For this scenario, you apply a single torque to the “up” face. As with the other scenarios, to change the face the torque is applied to, change the “up” direction. To change the direction of the torque (clockwise vs counterclockwise), adjust the scale. The restraint is defined to be the opposite side of the applied torque.\\ +**Controls:** As with the other scenarios, to change the face the torque is applied to, change the “up” direction. To change the direction of the torque (clockwise vs counterclockwise), change the sign of the torque magnitude (+/-). The bottom faces of the model are restrained.\\ 
-**Usefulness:** This can apply to anything that spins. Examples include opening a jar, screwing a screw, or opening a doorknob. The twist scenario covers these situations. +**Usefulness:** This scenario can apply to anything that spins.
