Therefore, we will model the gravity at 90 degrees rotated to the model.

Now, we wonder about the simplifications we can make in the model.  We notice that the truss bars can be modeled as beams, and so we will replace the solid geometries with line bodies with a cross-sectional area. This will reduce and simplify the model, decreasing the computational time while keeping the same validity.

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.)

After opening and generating the import, you should see the entire geometry has been detailed in the window.  You should take this time to familiarize yourself with the structure.
