Press ENTER. Then in the Function Editor window, go to File > Save. Change the Save as type to All Files, and name the file vth.txt. Once you save, you may close ANSYS APDL. Now, open the text file you just created. We need to name the function. In the text file, use Replace to replace all instances of %_FNCNAME% with vth. Also, we need to alter the line {{add the line

Spar

We need to repeat the above step, creating a command for the spar, but this time the thickness will be constant. We will also have to make minute changes to the code to refer to the correct section. For simplicity, the code is posted below.
