For this particular problem, we are interested in creating a grid style of mesh that can be mapped to a rectangular domain. This meshing style is called Mapped Face Meshing. In order to incorporate this meshing style (Click) Mesh Control > Mapped Face Meshing as can be seen below.

Now, the Mapped Face Meshing still must be applied to the air field geometry. In order to do so, first click on the surface body(filled rectangle), which should then highlight green. Next, (Click) Apply in the Details of Mapped Face Meshing table, as shown below.

Now, generate the mesh by clicking Mapped Face Meshing Update.

Edge Sizing

The desired mesh has specific number of divisions in the x direction and a specific number of divisions in the y direction. In order to obtain the specified number of divisions Edge Sizing must be used. The divisions in the x direction will be specified first. Now, an Edge Sizing needs to be inserted. First, (Click) Mesh Control > Sizing as shown below.

Now, the geometry and the number of divisions need to be specified. First (Click) Edge Selection Filter, . Then hold down the "Control" button and then click the bottom and top edge of the rectangle. Both sides should highlight green. Next, hit Apply under the Details of Sizing table as shown below.

Then, set Number of Divisions to 50 as shown below.



Next, set the Behavior to Hard as shown in the image below. This step will disable the ANSYS Mesher from overwriting any of our edge sizing specifications.



At this point, the edge sizing in the the y direction will be specified. Follow the same procedure as for the edge sizing in the x direction, except select only the left side instead of the top and bottom and set the number of division to 60. Remember to set the Behavior to Hard. Then, click Update to generate the mesh with the new specifications. You should obtain the following mesh.

Your mesh should now have 3,000 elements (50x60). In order to check how many elements your mesh has, expand Statistics under "Details of Mesh" as shown below.



Make sure that you also have 3,000 elements.
