$ifimpactuseEfgradiant  is the command to force the program to take the electric field of electrons and holes as <br><br>

 <math> \vec{E_{n}}  = \nabla E_{fn} </math>
 <math> \vec{E_{p}}  = \nabla E_{fp} </math>

Sometimes, this is a more reasonable approach to estimate the position of major electrons.
