COULOMB

Electric potential
near grading rings

COULOMB is an easy-to-use 3D electric field solver used for applications like:

High voltage shielding
Cables
Transformers
Insulators and bushings
Transmission lines
Lightning arresters
Printed circuit boards

Fast and accurate, COULOMB's calculations include electric field strength, transmission line parameters and capacitance.

Our powerful parametric solvers allow designers to automatically vary and experiment with geometry, materials and sources – reducing the tedious, repetitive task of fine–tuning multiple design parameters.

COULOMB reduces design time while improving product performance by letting you design via computer simulations thereby reducing costs and risks associated with physical prototyping.

COULOMB is also easy-to-learn, so you can focus on product development, not software training.
