    Returns:
    
    inertia with swapped axes
  - swap13
```
public FieldInertia<T> swap13()
```
    Swap axes 1 and 3.
    The instance is unchanged.
    
    Returns:
    
    inertia with swapped axes
  - swap23
```
public FieldInertia<T> swap23()
```
    Swap axes 2 and 3.
    The instance is unchanged.
    
    Returns:
    
    inertia with swapped axes
  - getInertiaAxis1
```
public FieldInertiaAxis<T> getInertiaAxis1()
```
    Get inertia along first axis.
    
    Returns:
    
    inertia along first axis
  - getInertiaAxis2
```
public FieldInertiaAxis<T> getInertiaAxis2()
```
    Get inertia along second axis.
    
    Returns:
    
    inertia along second axis
  - getInertiaAxis3
```
public FieldInertiaAxis<T> getInertiaAxis3()
```
    Get inertia along third axis.
    
    Returns:
    
    inertia along third axis
  - momentum
```
public FieldVector3D<T> momentum(FieldVector3D<T> rotationRate)
```
    Compute angular momentum.
    
    Parameters:
    
    rotationRate - rotation rate in body frame.
    
    Returns:
    
    angular momentum in body frame
