Summary

EPOTSUF has been enhanced to simulate charged dielectrics in electrostatic field analysis.

Explanation

The model of charging has been given only as a surface charge on a conductor, but now it can be analyzed by giving a surface charge on a dielectric surface.

When a charge density is given to a dielectric surface, the settings are the same as when a charge density is given to a conductor surface. “UNIT_TYPE” is newly added this time and can be set as =0:[$C$], =1[$C/m^2$].

How to use

See Handbook "17.10. Equipotential Surface Electric Field Sources" (this function makes it no longer an equipotential surface). Set as follows in Please set as follows (see Handbook "17.10. Equipotential Surface Electric Field Sources". This makes it no longer an equipotential surface).

* EPOTSUF * SERIES NO * SURFACE MAT ID * POT OR CHARGE * TIME ID * UNIT TYPE * EPOTSUF 3 1 0 2 1

To give an electric charge, set POT_OR_CHARGE = 0.

Note : that UNIT_TYPE is applicable only for electrostatic field analysis.
