Work with System Properties

You can set properties for the whole system, for the inlets and outlets, and also for the circuit elements.

Note: if the Dalton Browser is not available, click Browser in the Visibility panel to display it.

To select a calculation method for minor losses

1. In the Dalton Browser, expand the Properties category.
2. Select one of the following calculation methods:
   • Calculate except when K factor specified (Default)

     If this option is selected and no K factor has been supplied, the minor losses are calculated automatically. If K factors have been supplied, Dalton uses them to calculate the minor losses.

   • Don't calculate (use specified K factors)

     If this option is selected, the provided K factors are used to calculate minor losses.

   • Calculate & add them to the specified values If this option is selected, minor losses are calculated and added to the specified K factors

To set up inlets and outlets

You must set up at least one inlet and one outlet.

1. In the Dalton Browser, expand the Boundary Nodes category, to display the list of nodes available in the circuit.
2. Select the node that you want to use as an inlet, and then expand its content.
3. Select Inlet from the Type list.
4. Select a type of constraint for the node from the Constraint list, and enter a value for this constraint if required.
5. If necessary, modify the temperature of the fluid.
6. Repeat the steps above to create an outlet, but this time select Outlet from the Type list.
