Geometry
| Note |
|---|
The Geometry of the Tertiary Truss is the most complicated part of the design process. Many hours were spent creating the Solidworks geometry for the truss. This requires much time and practice in Engineering Design. However, this tutorial focuses on properly analyzing the structure, not creating it from scratch, so we will provide the created geometry. ANSYS is able to import Solidworks files directly, however, it also requires the Solidworks program to be installed on the same machine, so we provide the file in .STEP format, the "neutral" format for computer modelling.

Unzip the folder, and open up ANSYS. Use the import button to open up the file. (Remember to select "geometry file" from the drop down menu, so you can see .STEP files.)

For users of ANSYS 15.0, please check this link for procedures for turning on the Auto Constraint feature before creating sketches in DesignModeler. |
Line Body Truss
1. Parts
Part groupings are ways for ANSYS to automatically group pieces together and create automatic connections. We should create 2 part groups: the Truss K-1, and the Tertiary Subframe Surface.
...
Lastly, remember to show all the hidden parts. Remember to keep the imported Truss (as machined) parts suppressed. Suppress the Line bodies created by the above step.
