Description

The component Elbow is a valid model for Elbow angle between 30° and 120°.

Please consider: The component was modeled in order to consider the pressure losses of sharp edged elbows. 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.
