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.

Dimensioning
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. First, click on the "Constraints" tab, 
, then click on the "Equal Length" button, 
. Now, click on the two vertical sides of the rectangle you drew, then click on the two vertical lines you drew. Next, click on the "Dimensions" tab, 
, and select "General", 
. Now, click on bottom left vertical line and click once more to place the marker. Repeat this action with the upper left vertical line and the top horizontal line. Your Design Modeler window should look similar to the image below.
Now, the lengths need to be inputted. Input the length of the sides in "Details View" table. Input 3m for the length of the two vertical dimensions, and input 4m for the length of the horizontal line as shown below.
