TITLE: Flow in Pipe Using Unstructured MultiBlock Grid:
Input-Library Case, B582

DATE: 1996 PHOENICS VERSION: 2.2.1
PURPOSE OF THE CALCULATIONS:
- The problem considered is 3-dimensional, steady, laminar, isothermal flow in a circular
pipe with a 90 degree bend.
- The main objective of the calculations is to show the capabilities of the Generalised
Colocated Velocity (GCV) solver.
FLOW AND COMPUTATIONAL DETAILS :
- The pipe geometry is constructed of five separate blocks. A central cartesian block is
surrounded by four polar-style blocks. This creates an unstructured grid, even though each
block is structured within itself.
The images show the geometry with multi-block structure:
