• 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.

• 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:
