h1. Pre-Analysis & Start-Up

h3. Open ANSYS Workbench

Open ANSYS Workbench by going to Start > ANSYS > Workbench. This will open the start up screen seen as seen below

!OpenANSYS.png!

To begin, we need to tell ANSYS what kind of simulation we are doing. If you look to the left of the start up window, you will see the Toolbox Window. Take a look through the different selections. We are doing a modal analysis simulation. Load the {color:#990099}{*}{_}Modal(ANSYS){_}{*}{color} box by dragging and dropping it into the Project Schematic. 

!Start Up Screen 2.png!
 
Name the project {{Modal Analysis of an Airfoil}}. Now we need to specify what type of material we are working with. Double click {color:#990099}{*}{_}Engineering Data{_}{*}{color} and it will take you to the Engineering Data Menus.

If you look under the _Outline of Schematic A2: Engineering Data_ Window, you will see that the default material is Structural Steel. The Problem Specification specifies the material's Modulus of Elasticity and Poisson ratio. To change the material, first right click structural steel under the _Outline of Schematic A2: Engineering Data_ Window and delete it. To add a new material, click in an empty box and give it a name. We will be using 6061-T6 Aluminum. Name the material {{Al 6061-T6}}. On the left hand side of the screen, go to {color:#990099}{*}{_}Physical Properties >  Density{_}{*}{color} to define the density. Set the density as .0975 lb/in^3. Next, go to {color:#990099}{*}{_}Linear Elastic > Isotropic{_}{*}{color} to specify E and {latex}$\nu${latex}. Set the Elastic Modulus as 1e7 psi, and set the Poisson Ratio to .33.

8==DUnits}
There is no need about using one unit system in ANSYS. If you input the geometry in metric units and the material properties in English units, ANSYS will still calculate the correct results as long as you specify units.
{note}

Now that the Material has been specified, we are ready to load the geometry in ANSYS.
