What's Under the ANSYS Blackbox?
To understand the framework of what's under the ANSYS blackbox, go through the videos in the “What’s Under the Blackbox” section of our free online course on ANSYS-based simulations. Registration is required to access this course. We'll be using this framework in this tutorial.

Check Your Understanding
One or more of the following statements is/are true. Select which statements are true.
- 3D Elasticity theory makes the assumption that plane sections remain plane whereas the Euler-Bernoulli beam theory doesn’t make this assumption.
- In Euler-Bernoulli beam theory, the Poisson's ratio is assumed to be zero.
- If we have 4 nodes instead of 3, ANSYS will need to determine 8 parameters (4 y-displacements and 4 rotations) either from the essential boundary conditions or by solving a set of algebraic equations.
- If we have 4 nodes instead of 3, the number of algebraic equations that ANSYS will need to solve simultaneously will be 5.
- We have to determine the y-displacement of the midline at locations between the nodes using interpolation. This interpolation is given by a second-order polynomial.

Engineering Data
The specific properties of the material Cornellian needs to be inputted into ANSYS. Start by right clicking on Engineering Data and then clicking on "Edit.." as seen below.
At this point a new window will open. Under "Outline of Schematic A2: Engineering Data" there will be a box with text inside that says "Click here to add a new material". Click on that box and type in "Cornellian" and then press enter.
Now, expand the "Linear Elastic" tab on the right and double click on "Isotropic Elasticity".
Now, the properties of "Cornellian need to be inputted in to the "Table of Properties Row 2: Isotropic Elasticity" window. Set the temperature to 25 degrees C., set Young's Modulus to 2.8x10^(10) and set Poisson's Ratio to 0.4 .
At this point the project can be returned to. Click on the Return to Project button, .
