Download Single Material Pair Data

Download simulation-ready single material pair data from AMDC Stick-Slip database to Squeak and Rattle Director (SnRD).

On the AMDC home page, click Stick-Slip database > Go to Altair's Stick-Slip database.
Select a material pair and then click Details.
An Info tab opens to the right displaying the general information of the selected material pair.
Note: Click to view the material information in full screen mode.
Click the CAE Model tab.
The Select Software displays Squeak and Rattle Director as already chosen.
Select a scenario from the Scenario list. By default, the Worst Case Scenario is chosen.
Figure 1. Material Pair Preview
The Material Pair Preview displays the following:
- Material Pair 1 Worst Case Scenario (selected by default): Displays important material properties including impulse rate value for the worst-case scenario for the selected material pair.
- Material Pair 2 Best Case Scenario: Based on your selection, AMDC suggests the opposite scenario. In the current example, AMDC suggests best-case scenario with lower impulse rate value and other material properties for the same selected material pair.
To download only a single pair of the selected scenario material data, click Remove from Material Pair 2 preview.

Figure 2. Remove Material Pair 2

The second material pair suggested by AMDC will be removed.

Click Download to export the material pair data as a CSV file to the SnRD director.
