GPU-Accelerated Simulation

Charged Particle Simulation,
GPU-Fast.

The modern replacement for SIMION and expensive EM solvers. Define your electrode geometry, set your voltages, and simulate ion and electron trajectories. GPU-accelerated, cloud-native.

The Problem

Simulation tools haven't kept up
with your hardware.

SIMION's architecture dates back decades. COMSOL and CST Studio cost tens of thousands per seat. None of them leverage GPU acceleration. Meanwhile, your workstation has thousands of GPU cores sitting idle. It's time for charged particle simulation to catch up.

Features

Built from scratch for modern hardware.

100× Faster Than Legacy Tools

Trajectory stepping is embarrassingly parallel. We run hundreds of thousands of particles simultaneously on your GPU. What takes SIMION hours finishes in seconds.

Validated Accuracy

Validated against published experimental datasets. Field solutions verified against analytical benchmarks. Trajectory results match legacy tools within experimental noise.

Cloud-Native

No local GPU needed. Run simulations on cloud GPUs that scale to your workload. Pay only for compute you use.

API-First Design

Designed from the ground up for programmatic access. Define geometries, submit jobs, and retrieve results via a Python SDK and REST API — coming soon.

 import ionforge

job = ionforge.simulate(

  geometry="trap.step",

  electrodes={

    "endcap_1": +500,

    "endcap_2": -500,

    "ring": 0,

  },

  particles="Ca+",

  n_particles=100_000

)

trajectories = job.trajectories()

field = job.field_map()

Electrode Geometry

Define electrode surfaces by drawing polygons, importing CAD files (STEP, DXF), or assigning voltages to imported geometry. Ground potential defined by bounding box.

Real-Time Dashboard

Watch simulations converge live. Interactive trajectory plots, 2D field maps, and exportable datasets, all from your browser.

How It Works

Three steps. Zero friction.

Define

Specify your electrode geometry and voltages through the dashboard or API. Import CAD files directly or draw surfaces interactively.

Simulate

Your job runs on cloud GPUs. The EM field solver computes the electric potential across your geometry. Ions and electrons are then stepped through the field to produce trajectories.

Analyse

Explore trajectory plots, field maps, phase space distributions, and transmission efficiency. Export data as CSV, JSON, or via API.

FAQ

Questions & answers.

IonForge solves the Laplace equation to compute electric potential fields and steps particles through the resulting force field. Field solutions are verified against analytical benchmarks, and trajectory results are validated against published experimental datasets. Results match legacy tools within experimental noise.

No. IonForge runs on cloud GPUs and you access everything through a web dashboard or REST API. No local GPU, no driver configuration, no CUDA toolkit. Your simulations run on NVIDIA A100 or H100 GPUs in our infrastructure.

IonForge supports ions and electrons as particle types. Electrode geometries can be defined as arbitrary polygonal surfaces drawn interactively in the dashboard, or imported from CAD files (STEP, DXF). Ground potential is defined by the simulation bounding box.

Yes. All simulation data is encrypted in transit and at rest. Your parameters and results are isolated per-organisation and never shared or used to train models. Enterprise customers can request dedicated VPC deployment for additional isolation.

Pricing is still being finalised. Early access members will receive founding-member pricing, locked in for life. Join the waitlist to be notified when plans are announced.
