When computing a model I notice that I getting reverse flow in conduit where there should not be reverse flow? How can I correct this?
This issue may be resolved by going into the calculation options (Analysis > Calculation Options) and setting the property for "Correct for partial Area Effect?" to True. What this option does when set to true is when two or more rational flows enter a single node the GVF Rational solver will adopt the system time that produces the largest rational flow. A larger 'partial area' flow will be carried downstream until the 'total area' flow exceeds it.
