Mesh of coolant flow field inside fuel rod bundle. An imaginary hole linking the inside and outside of a fuel rod
One of my colleagues, Bing DONG (email@example.com), is working on transient CFD simulation of a flow field inside a fuel rod bundle of a pressurized water nuclear reactor system. He sets up an imaginary hole on the cladding of the fuel rod. After discussing the strategy of mesh generation, I found that it was interesting and a good chance for an everyday practice. I borrowed the geometry form him and generated a sample mesh for myself, just for fun.
The software is ANSYS ICEM. The mesh consists of pure hexahedral grids.
