Geometry
Assume that the cross-section is square. Then, to get the right values of EI and EA, you need to pick:
- Each side of the square is 0.346 m
- The Young's Modulus E is 2.08e10 Pa
Don't forget to assign the Young's modulus later in the Physics Setup.

Line Sketching
First, click on the sketching tab, 
, which is located underneath the "Tree Outline". Next , click on the rectangle button, 
, and draw a rectangle somewhere above the x axis in the top right quadrant of the XY Plane as shown below.
Next, click the line button, 
, and draw two vertical lines that connect the bottom left and the bottom right corners of the rectangle to the x axis. Remember that a "P" should appear when the mouse is directly over a rectangle corner and a "V" should appear when the line your drawing is vertical. Lastly, make sure that a "C" appears before you click on the x axis to terminate the line segments. You should now have an image comparable to the one below.
Now, the dimensions of the plane frame structure will be inputted into ANSYS. The plane frame structure has symmetry in its geometry, so "equal length" constraints will be used in order to shorten the dimensioning process.
