Zero-Length Connector Configurations

Pipes defined as zero-length connectors are only allowed to be used in limited cases. If the zero-length connector is used for a restricted case Impulse will show the following message: "Zero-Length Connector configurations that are not allowed for transient simulation exist."

To resolve the above error navigate to all pipes/junctions indicated by Impulse and disable the zero-length connector feature so that the restricted configuration no longer exists at those pipes/junctions. For a full list of restricted configurations see the discussion of zero-length connectors in the Pipe Model topic.

When changing the zero-length connector pipes to short pipes be careful to choose a reasonable pipe length to help avoid significantly long run times. See the topic on the affects of using unusually short pipes for suggestions on alternate ways to configure the model.
