Kratos FlowGraphA visual node editor for KratosMultiphysics

Wire together solvers, materials, processes and outputs on a canvas, then generate a ready-to-run Kratos ProjectParameters.json — no hand-editing JSON.

🧩

Visual, node-based configuration

Build a Kratos simulation by connecting nodes on an infinite canvas. The graph is the configuration — every node maps to a block of the resulting ProjectParameters.json.

First graph walkthrough

⚙️

Rich Kratos node library

Analysis stages, orchestrators, fluid/structural/thermal/potential-flow solvers, serial & MPI linear solvers, constitutive laws, boundary-condition processes, modelers and output processes.

Round-trip with existing cases

Import an existing ProjectParameters.json and FlowGraph reconstructs the node graph automatically, or export the current graph as a zipped, ready-to-run case.

Quick start

npx @kratos-flowgraph/flowgraph

Then open http://localhost:8182 in your browser.

FlowGraph is a browser-based editor served by a small Node/Express backend. It targets KratosMultiphysics "Problemtypes": instead of writing ProjectParameters.json by hand, you assemble it visually and let FlowGraph produce the JSON (and material files) for you.
