Automatic Meshing for Regions

The automatic mesh sizes for faces and edges when using the coarse, standard and fine mesh options are dependent on the solver method.

For regions, the wavelength (λ) is determined based on the maximum simulation frequency and the medium properties of the region. The specified lengths will be applied to the tetrahedron edge lengths.

Type Fine Standard Coarse
Finite element method (1st order FEM) $\frac{\lambda }{15}$ $\frac{\lambda }{10}$ $\frac{\lambda }{8}$
Finite element method (2nd order FEM) $\frac{\lambda }{12}$ $\frac{\lambda }{8}$ $\frac{\lambda }{6}$
Volume equivalence principle (VEP) $\frac{\lambda }{16}$ $\frac{\lambda }{12}$ $\frac{\lambda }{8}$
