How to apply color coding to pipes based on the flow direction?This would be helpful to view when pipe flow reverses while viewing results for an extended period simulation.
First, make sure the pipes have the orientation you want.
Then create a color coding for pipes that is based on the "Flow" property, do not use "Flow (absolute)". The model will need to be computed for the color coding to display. The following image shows how to set this up in the element symbology color coding edit dialog.
