3D geometry for 2D simulation
Title
Question
The channel flow shows a 2D geometry, whereas the channel geometry is shown to be 3D. Why is this?
OpenFOAM-version-7 Creating-2D-Channel-Geometry-and-Mesh-in-OpenFOAM 01-02 min 10-20 sec
Answers:
OpenFOAM only allows computations in a 3D geometry. Therefore, we create a 3D geometry for this 2D problem. The simulation, however, is made 2D by considering only one cell across the z direction to make the simulation 2D in xy-plane. The same has been explained later in the tutorial.
