From the above figure, the vertex locations are as follows:
Vertex | x | y | |
v1 | 0 | 0 | |
v2 | 0.5*cos30 cos(pi/6) | 0.5*sin30 sin(pi/6) | |
v3 | cos30 | cos(pi/6) | sin(pi/6) sin30 |
v4 | cos30 cos(pi/6)-0.25*sin30 sin(pi/6) | sin(pi/6) sin30+ 0.25*cos30 cos(pi/6) | |
v5 | cos30 cos(pi/6)-0.5*sin30 sin(pi/6) | sin(pi/6) sin30+ 0.5*cos30 cos(pi/6) | |
v6 | 0.5*(cos30-sin30(cos(pi/6)-sin(pi/6)) | 0.5* (sin30+cos30sin(pi/6)+cos(pi/6)) | |
v7 | -0.5*sin30 sin(pi/6) | 0.5*cos30 cos(pi/6) | |
v8 | -0.25*sin30 sin(pi/6) | 0.25*cos30 cos(pi/6) |
There are two options for creating the eight vertices: we can use the mouse after pressing the Click SD Points button, or we can enter the coordinates directly into the edit boxes under Vertex positions. We'll use the latter option. Enter the above coordinates in the corresponding edit boxes under Vertex positions as shown below. You can use MATLAB expressions within these boxes. For instance, for the x coordinate of the fifth vertex, enter cos(pi/6)-0.5*sin(pi/6) under Xpos (note that angles need to be entered in radians). Recall that, after you have entered a value, you can use the Tab key to jump to the next box.

Let's keep the fun going by moving on to Step 3 where we will specify inputs such as material properties and boundary conditions.
