The viscosity look-up table (viz. Viscosity Selection Table), a list of typical viscosity coefficients for specific liquids (at a certain temperature), is accessible from the System tab of the Model Settings box.
In order to select a specific viscosity, the procedure is as follows:
1. Place the cursor on the fluid to be selected.
2. Click on OK, and the appropriate viscosity will be selected and entered into the Viscosity field.
