Multiphase Flow for a Fuel Tank: Exercise 3—Preparing the Mesh
Generating the Mesh
1. In the Flow Analysis Tree, select Domains.
2. In the Properties panel, Mesh tab, for Mesh Generation, type the following values:
◦ Maximum Cell Size—0.008
◦ Minimum Cell Size—0.0003
◦ Cell Size on Surfaces—0.002
◦ Create a Refinement Zone—Cylindrical Zone
▪ Cell Size—0.002
▪ Top Circle Center—4.0140, -2.6150, 0.2656
▪ Bottom Circle Center—3.6139, -2.6140, 0.1586
▪ Zone Radius—0.03
