Fitting


Model description

This element represents a change in profile type and/or a change in the profile diameters. Dependent on the difference between the profile dimension at the inlet and the outlet, the model implemented in the element types Extension and Reduction are used.

The inlet and outlet area $A_1$ and $A_2$ are calculated based on the profiles of the up- and down-stream elements. Hence, this element type is required to be positioned inbetween two elements. The framework will automatically place fittings inbetween two elements with different profiles.
