ICEM CFD Introductory Course Introduction to Hexa –Workshop 4 Elbow Junction

§Blocking Strategy
In this Elbow geometry there is an cylindrical hole through the geometry.
Such Elbow can not be captured well with single Ogrid through out the elbow pipe. This is because grid lines need to be align with hole
To resolve this we will be creating an L-shaped blocking initially with an O-grid only in one straight section to capture the cylindrical hole.
Then we create final ogrid through out the elbow pipe which align well with elbow surface
§Begin blocking
Select Blocking > Create Block > Initialize Blocks
Change Type to 3D Bounding Box
Click Apply
This creates one block which encloses the entire geometry
Curves automatically change color (colored separately instead of by part) to allow you to see where the ends of curves are
