# Automatic Meshing for Wires

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

For wires, the wavelength (λ) is determined based on the maximum simulation frequency and the surrounding medium.
Type Fine Standard Coarse
Method of moments (MoM) $\frac{\lambda }{25}$ $\frac{\lambda }{12}$ $\frac{\lambda }{8}$
