What is 1D/System CFD? 1

[Simba1978]

When explaining what 1D CFD or System CFD is , i struggle to define it clearly.

1D software include Pipeflow, Olga, Wanda and Flowmaster

Does anyone have a good description technically and in Layman terms to describe this type of analysis?

Thank you in advance

1D Down the pipe direction only, all fluid particles are considered to be in parallel flow only.

2D down the pipe plus considering (turbulent) flows in the wall to pipe centerline direction, or flow around an aircraft wing x-section.

3D flow around a wing x-section plus perpendicular wing tip vorticies in the wing tip to fuselage direction.
