The base size for this example is based on the size of the diameter of the inlet and all other relative meshing values are scaled from this. We could have used absolute sizes instead. To measure any part of the geometry, you can use the Measure distance between two points 
toolbar button and click on any two points on the surface. The distance between the points will be reported in the output window in meters.
To set the reference value parameters, click on the relevant node and enter the above values in the Properties window. For example, to set the base value, do the following:
- Click on the Reference Values>Base Size node.
- In the Properties window, set Value to
0.06 m.
- Repeat this for the other nodes in the list using the values supplied in the table.
