This function modifies the calculation method of mobility. Both electron and hole mobilities are considered electrical field-dependent terms with the default. However, you can define this function by using function usefielddependent_n(indEl, matind ,Ex,Ey,T,xp,yp) and function usefielddependent_p(indEl, matind, Ex, Ey, T, xp, yp).
The default follows the equation:

\mu=\mu_0\times exp(\beta\sqrt{F})

,

where

$usemunpfunc
    1   $\mu_e$    $\beta_e$    $\mu_h$    $\beta_h$
