The geometry for the example will be created just as in the Cavity Flow example, using the Preprocessor module. The geometry will again resemble a box, but with a step at its bottom surface (Figure 45).
By entering the points with the co-ordinates given below, then joining them into lines and finally creating the control surface, we will obtain the geometry shown in Figure 45. For details on creating the geometry, please refer to the section Geometry definition of example 1.
Point Nš: | X Coordinate | Y Coordinate |
1 | 0.000000 | 0.500000 |
2 | 4.000000 | 0.500000 |
3 | 4.000000 | 0.000000 |
4 | 20.000000 | 0.000000 |
5 | 20.000000 | 2.000000 |
6 | 0.000000 | 2.000000 |
