The method

Physics you can audit,
precision that learns.

SimBond bonds a proven physics baseline with machine learning — combining the trust of an explicit formula with the accuracy of 560 full FEM simulations.

STAGE 01

Physics foundation

An improved SRSS formula with coupling coefficients establishes a transparent, code-aligned resistance baseline — no black box.

MethodSRSS
STAGE 02

ML residual correction

A physics-informed neural network (PINN), trained on 560+ in-house FEM cases, learns the residual the physics misses, sharpening every prediction.

Why SimBond

The accessible alternative
to desktop FEM.

Legacy connection tools are powerful but heavy — desktop-bound, per-seat, and opaque. SimBond keeps the rigor and drops the friction.
