This method category is used to specify the direction in which the Bifurcation solves (downstream given inflow and one outflow or the outflow fractions; upstream given the outflows).

For basic Simulation runs, direction does not make a difference, and the default method should remain selected.

In Rulebased Simulation, however, you may need to limit the Bifurcation to a downstream direction only. If necessary, the Bifurcation can be forced to solve for only Outflow1 or Outflow2 using the appropriate method.

The Solve Upstream or Downstream method is the default user method. If this method is active, it allows all dispatch methods to be active. No slots or calculations are specifically associated with this method.

This method allows the Bifurcation object to only solve in the downstream direction with the following dispatch methods: Solve given Inflow, Outflow2; Solve given Inflow, Outflow1; or Solve given Inflow. No slots are specifically associated with this method.

This method allows the Bifurcation object to only solve for Outflow1 using the Solve given Inflow, Outflow2 dispatch method. No slots are specifically associated with this method.

This method allows the Bifurcation object to only solve for Outflow2 using the Solve given Inflow, Outflow1 dispatch method. No slots are specifically associated with this method.
