Indicates the direction cosines for the heat exchanger centerline. For example:
When the centerline is along the X-axis:
Centerline Direction Cosine X = 1.0
Centerline Direction Cosine Y = 0.0
Centerline Direction Cosine Z = 0.0
When the centerline is along the Y-axis:
Centerline Direction Cosine X = 0.0
Centerline Direction Cosine Y = 1.0
Centerline Direction Cosine Z = 0.0
When the centerline is along the Z-axis:
Centerline Direction Cosine X = 0.0
Centerline Direction Cosine Y = 0.0
Centerline Direction Cosine Z = 1.0
