Choice of cell size w.r.t size of the domain for meshing

mazhar16823 · June 7, 2020, 14:04

Hi everyone,

Is there any rule of thumb or usual practice to know what maximum and minimum cell size should be chosen for meshing the domain w.r.t its size. For instance if the geometry length (L) is 30 m and domain size is 8Lx3L. Which maximum/minimum cell size should be chosen to mesh the domain (not the geometry)?

Or this all comes from the personal experience?

Thanks for your time.

Based on the grid independence study, one gains experience.
