Step 2: Modify and read input file

...

Enter the location of the folder shell2 that you just created as your Working directory by browsing to it.

Enter shell2 as your Initial jobname. Click on Run.

Resize the ANSYS windows as shown in this snapshot so that you can read instructions in your browser window and implement them in ANSYS.

Symbols menu: For Boundary condition symbol, select All Applied BCs. For Surface Load Symbols, select Pressures and under Show pres and convect as, select Arrows. Click OK.

 

We see that the symmetry and clamped BC's haven't been applied at the correct locations. The pressure has been applied only over part of the facesheet. We'll fix these mistakes below.

A tip from a battle-hardened user: you have to be careful about recycling the log file when the topology of the geometry changes. For instance, if you change H2 and H3 such that the y-stiffeners become wider than the x-stiffeners, the topology changes significantly. In this case, unless you are a power user, it might be advisable to use the log file only for steps 1-3 (as you look through the log file, you should be able to hone in on where step 3 ends and step 4 begins).Then, go through steps 4-6 in the GUI and generate clean new lgw/input files.
