5.After making a selection, answer the question in the Dialog menu bar with Yes or Cancel.

Note:

•The default box is rectangular. Use the SHIFT key to define a polygon box.
•A surface must be selected before any vent hole, injector, or bag can be created.
6.Set the necessary values in the different fields which are under the surface selection.
7.Select the Vent Holes sub-folder (available for GAS, AIRBAG and COMMU monitored volumes):
8.Click boxNewGeneral-24 to create a new vent hole.
9.Select Located surface to define a vent hole in a specific area of the monitored volume surface.
10.After making a selection, answer the question in the Dialog menu bar with Yes or Cancel.
11.Select unlocated surface to defined a generic vent hole.
12.Set the necessary values in the different fields which are under the surface selection.
13.Define the necessary functions:
•Por. vs Time = porosity versus time
•Por. vs Pressure = porosity versus pressure
•Por. vs Area = porosity versus area
14.Click Save to save the vent hole.

or

Click Cancel to cancel the vent hole creation.

Note:If the new vent hole is incorrect, HyperCrash will indicate this and request correction of the errors.
•To modify a created vent hole, select the vent hole (only one) in the window list.
-Click reviewGeneral-24 to see the vent hole and edit it

17.Set the necessary values in the different fields which are under the surface selection.
18.Define the necessary functions:
•Mass of inj. vs. Time = mass of injected gas versus time
•Temp. vs. time = temperature of injected gas versus pressure
•P(t) = pressure versus time
•P(theta) = pressure versus angle
•P() = pressure versus distance
19.Select the type of mass input:
•Mass versus time: toggle button switched off.
•Mass flow versus time: toggle button switched on.
20.In case of jetting:
•Toggle the button, Jetting ON / OFF.
•Define the local skew of the jetting by clicking selectGeneral-24 and selecting three nodes on the screen.
•Define the function P(t) = pressure versus time.
•Define the function P(theta) = pressure versus angle.
•Define the function P() = pressure versus distance.
21.Click Save to save the injector.

or

Click Cancel to cancel the injector creation.

Note: If the new injector is incorrect, HyperCrash will indicate this and request correction of the errors.
•To modify a created injector, select the injector (only one) in the window list.

-Click deleteGeneral-24 to delete the injector(s).
22.Select the Bags sub-folder (available for COMMU monitored volumes):
23.Click boxNewGeneral-24 to create a new bags communication area between bags.
24.Select the monitored volume from the monitored volumes list (type: AIRBAGS or COMMU) which will communicate with the edited one.
25.Click Select in order to validate the monitored volume selection.

The common surface between the bags is automatically highlighted.

26.Use the following functions listed above in Step 4 to modify the communication surface.
27.After making a selection, answer the question in the Dialog menu bar with Yes or Cancel.
28.Set the necessary values in the different fields which are under the communication surface selection.
