You might ask – “why not load each element shape as a separate zone?” For this dataset, you’d likely save some space if you split out the tetrahedrons into a separate FE-Tetrahedron zone – since the connectivity would only specify 4-nodes per cell rather than 8-nodes. That amounts to a lot of wasted space in the data file and in RAM when loaded into Tecplot 360. Now, consider that you have 183 million elements, each of which has 2 – 4 extra integers in the connectivity arrays. These cells are stored as Finite-Element Brick but are physically a mix of Prisms (near the surface), Tetrahedrons (far field), and Pyramids. The dataset pictured here (courtesy Metacomp Technologies) is composed of 183 million volume cells. This dataset (courtesy Metacomp Technologies) is composed of 183 million volume cells.
