(volume_constraint:min_vol)=
### min_vol
Minimum volume for the sum of all reservoirs connected to this constraint (xUnit: NO_UNIT, yUnit: MM3)


(volume_constraint:max_vol)=
### max_vol
Maximum volume for the sum of all reservoirs connected to this constraint (xUnit: NO_UNIT, yUnit: MM3)


(volume_constraint:min_vol_penalty)=
### min_vol_penalty
Given penalty cost for having a sum volume below the min_vol (xUnit: NO_UNIT, yUnit: NOK/MM3)


(volume_constraint:max_vol_penalty)=
### max_vol_penalty
Given penalty cost for having a sum volume above the max_vol (xUnit: NO_UNIT, yUnit: NOK/MM3)
