* one control can be active at a time, indicated by current. The
|
|
* meaning of each control's target value depends on the control type:
|
|
* BHP -> target pressure in Pascal.
|
|
* RESERVOIR_RATE -> target reservoir volume rate in cubic(meter)/second
|
|
* SURFACE_RATE -> target surface volume rate in cubic(meter)/second
|
|
* The sign convention for RATE targets is as follows:
|
|
* (+) Fluid flowing into reservoir, i.e. injecting.
|
|
* (-) Fluid flowing out of reservoir, i.e. producing.
|
|
* For *_RATE controls, the distribution of phases used for the control
|
|
* is also needed. For example, a total rate control should have 1.0
|
|
* for each phase, whereas a control on oil rate should have 1.0 for
|
|
* the oil phase and 0.0 for the rest. For BHP controls, this is unused.
|
|
* The active control acts as an equality constraint, whereas the
|
|
* non-active controls should be interpreted as inequality
|
|
* constraints (upper or lower bounds). For instance, a PRODUCER's
|
|
* BHP constraint defines a minimum acceptable bottom-hole pressure
|
|
* value for the well.
