protected FieldAbstractCartesianCost(String name,
                                     T massFlowRateFactor)
```
    Constructor.
    
    Parameters:
    
    name - name
    
    massFlowRateFactor - mass flow rate factor
- Method Detail
  - getAdjointName
```
public String getAdjointName()
```
    Getter for adjoint vector name.
    
    Specified by:
    
    getAdjointName in interface FieldCartesianCost<T extends CalculusFieldElement<T>>
    
    Returns:
    
    name
  - getMassFlowRateFactor
```
public T getMassFlowRateFactor()
```
    Getter for mass flow rate factor. It is negated and multiplied by the thrust force magnitude to obtain the mass time derivative. The fact that it is a constant means that the exhaust speed is assumed to be independent of time.
    
    Specified by:
    
    getMassFlowRateFactor in interface FieldCartesianCost<T extends CalculusFieldElement<T>>
    
    Returns:
    
    mass flow rate factor
  - getFieldAdjointVelocityNorm
```
protected T getFieldAdjointVelocityNorm(T[] adjointVariables)
```
    Computes the Euclidean norm of the adjoint velocity vector.
    
    Parameters:
    
    adjointVariables - adjoint vector
    
    Returns:
    
    norm of adjoint velocity
