Cerbsim - Customized Simulation Tools#

Simulation in the hands of your product engineers.

We build in-house simulation apps together with your simulation experts. Your design engineers compute losses, heating, fields and flow on their own, and the design cycle gets shorter.

E-Motor Studio, a cerbsim simulation app

Trusted by industry and research

The design-cycle bottleneck

The queue between design and validation costs you weeks. An app removes it.

Design → Simulation dept. queue → Report → Iterate

Design ⇄ Validate yourself

How it works

Built with your simulation experts. Used by every designer.

1

Your expert defines the method

The methodology stays yours. Your simulation expert sets the models, the material data and the validation cases, and becomes the owner of the platform instead of the bottleneck for every calculation.

2

We build the app around it

Guided inputs in the language of your design department, import from the sheets you already use, sensible defaults, automatic checks. Easy to use, hard to use wrong.

3

Every designer runs it

On the desktop or in the browser. Design engineers check losses, heating, fields and flow themselves, while designing, not weeks later.

See it live: E-Motor Studio

Our public demo app. Design a permanent-magnet synchronous motor straight from its design sheet: automatic geometry and meshing, magnetostatic FEM over one electrical period, torque, back-EMF, cogging, efficiency and design checks. The field is rendered live in your browser.

E-Motor Studio: simulation results with flux density field view

Runs entirely in your browser. First start loads about 100 MB and takes a minute.

Note, E-Motor Studio is a demonstration toy, small enough to run in a browser tab. The apps we build for clients go much deeper. Solvers tuned to one specific problem, one machine, one product line. That focus is exactly where we stand out.

Where this pays off

Wherever a recurring calculation sits between your designers and their next iteration.

Flux density in a permanent-magnet motor

Electric machines & drives

Torque, losses, heating, demagnetization

Design-sheet apps for motor and transformer development, electromagnetic and thermal, validated against your measurements.

Hydro, fans & turbomachinery

Air and water flow, pressure, structural loads

Apps that let designers check blade, runner and casing variants without waiting for the CFD group.

Chip package with pin-fin heat sink, temperature field

Cooling & data-center thermal

Heat removal, hot spots, operating points

Thermal design apps for engineers who size cooling every week, not once a year.

Induction & power electronics

Induction heating, transformers, chokes, coupled EM-thermal

Low-frequency electromagnetics packaged so process engineers can tune coil and workpiece themselves.

High-frequency EM & waves

Antennas, scattering, resonators, EMC

High-order solvers for wave problems, packaged so your engineers can sweep designs themselves.

Why not generic CAE?

Simulation apps without the license meter.
