Description

The component Bend is a valid model for Bend angle between 15° and 180°.

Please consider: The component was modeled in order to consider the pressure losses of well rounded bends. However, the use of the component can lead to extremely long simulation times, since a small stepsize must be selected due to the low resistance of an elbow.
