Attempt to evaluate negative power of zero.

Please login with a confirmed email address before reporting spam

Hi all,

I'm trying to do corona discharge with the electrostatic and transport of dilute species modules, and currently got stuck with this probelm: Attempt to evaluate negative power of zero. - Function: ^ Failed to evaluate temporary symbolic derivative variable. - Variable: comp1.es.normE@VDN$z@VDN${conj@16} - Defined as: (((realdot(comp1.es.Er,comp1.es.Er)+realdot(comp1.es.Ez,comp1.es.Ez))^(-0.5))0.5)((-comp1.Vrz)+(-comp1.Vrz))

And also what does VDN mean?

Thanks so much!
