diTwoo
SIMULATE YOUR ENTIRE DESIGN, RIGHT INSIDE YOUR CAD TOOL.
An agentic engine for reaction-coupled multiphase transport simulation. Run thermal, fluid, and reaction simulations instantly without ever leaving your CAD workflow.
Complexity,
Simplified.
Simulation at the speed of thought!
Zero Exporting.
Zero Meshing.
diTwoo reads raw CAD geometry directly. No manual cleanup, no defeaturing, no round-trip to a separate tool.
Adaptive
Grids Instantly
No traditional, error-prone meshing. diTwoo builds with recursive octree refinement automatically, resolution goes where the physics needs it most.
Built to be
Called.
Full API, SDK, and MCP access under everything we ship. Use the Fusion 360 extension, or DIY your own custom plug with API, SDK, MCP to use diTwoo from anywhere, call the same solver runs underneath either way.

You are building the world's most advanced hardware.
Why simulate it on software from the 90s?

High quality CFD runs take weeks on local CPU clusters. Supercharge your engineering to design faster than ever, so you can make decisions before you build anything.

Let's be honest, we've faced serious issues in mesh refinement around boundary layers, where 'Fine/Medium/Coarse' options just don't cut it. And probably node #1849318 is angry you looked at its neighboring node, forcing hours of manual cleanup. Getting a valid volume mesh takes longer than the solve itself. Leave it to Auto-AGR.

Legacy solvers choke on complex CAD, and modern solvers don't like .step, .stl, or .obj. We end up spending more time exporting/importing than closing the loop! diTwoo doesn't need ANY import/export. Pinky promise!

Coupling fluid, thermal, multiphase, and reaction chemistry is a NIGHTMARE, I've been there too! Flaky empirical equations break down fast. LBM naturally fixes these issues with its emergent physics! (Yes, I am aware of wall functions, and yes they are not resolved :P)

Tbh, I started writing my own solvers after seeing the prices of 'leading' commercial software. Pay for what you use with diTwoo, and any unused compute credits roll over to the next month. Cheers!
Simulate what others can't ;)
Built for the folks designing next-gen deep-tech and climate-tech systems. We're just as passionate about your mission as you are.
Unlike generalized solvers, diTwoo is built specifically for incompressible and low-Mach reacting flows. Where general-purpose Navier-Stokes trades accuracy for range, diTwoo trades range for fidelity, versatility, and emergent multiphase behaviors.
Small Modular Reactors
Simulate core thermal-hydraulics and coolant flow distribution directly from CAD. diTwoo's kinetic solver handles the complex reactor vessel geometries that break traditional mesh-based methods, without sacrificing fidelity on safety margins.
