Looking for recommendations for 2D (or 3D) electric field mapping software. I want to be able to populate a series of electrodes in a plane and understand the equipotentials present when these electrodes are driven to different voltages. Would like to model virtually first before realizing the design in a PCB/PWB to reduce cycle time. Must be low cost or FOSS software. Will be modelling fields in free-space and with patterns of electrodes, so no fancy lossy di-electrics or esoteric material need be supported.
