5th pillar

Parametric Study —
automate your design space.

Define a parameter range, set the number of steps, and let SimBond sweep your connection through our full FEM pipeline automatically. No manual reruns.

Sweep any parameter

Vary geometry, mesh density, solver tolerances, or load magnitude across a configurable range — any combination, any number of steps.

Full FEM per iteration

Each iteration runs the full build → mesh → solve → post chain on our engine. Results stream back as jobs complete.

Batch result table

Every run lands in a sortable results table — stress, displacement, convergence — ready to compare and export.

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.
