Integrated Modeling
Our integrated modeling framework delivers consistent, end-to-end physics calculations across devices ranging from small university tokamaks to future fusion power plants. Many of its capabilities can also be applied to stellarators and other MCF devices.
A new tokamak project starts with a very small team, no simulation tools, and no integrated pipeline between them — yet it has to assess feasibility quickly, prove the concept to investors, and make the foundational design decisions it can trust.
Our mission is to accelerate fusion companies by bridging world-class science with deployable, industry-ready solutions. From day one, we support tokamak and other MCF device builders with an experienced team and a verified and validated integrated modeling framework — and stay with you long term, through design, engineering, commissioning, and experimental operation.

What We Offer
Tokamak feasibility study
Before you commit to a design, we clarify the project vision and scope, assess feasibility, and develop a pre-conceptual design — simulating your device with NSFsim from the first step. We have completed 10+ feasibility studies of new fusion devices of various size, research and commercial purpose, so you know early what your device can deliver.
Tokamak design and engineering
Expert support across all phases of tokamak conceptual design, engineering integration, commissioning, and experimental operation — backed by our integrated modeling framework: multi-physics, time-dependent scenario analysis, disruption modeling (including 3D), SOL, divertor, and plasma-material interaction modeling, and much more.
Integrated modeling framework
NSFsim is the core of our validated and verified integrated modeling framework. It is an IMAS-compatible Grad-Shafranov code for 1.5D axisymmetric tokamak simulation with time-dependent transport and free-boundary evolution, coupled with TRAVIS, ASCOT5, TGLF, MISHKA, and other codes. Using a digital replica of the tokamak, it delivers a range of simulations, including scenario development, breakdown, disruptions and VDEs, equilibrium reconstruction, and more.
Agentic AI for integrated modeling
AI agents that support your team in integrated modeling and device operations: they analyze simulation and shot data together with papers and notes, run pre-defined skills and simulation tools, and write the plots, tables, and reports your physicists check. The same approach lets agents build reduced simulators through hypothesis-and-test loops, validated against reference simulation outputs.
