iteraSim Eddy — User Guide

Navigating Possibilities in Fluid Dynamics

iteraSim Eddy is a desktop application that drives OpenFOAM end to end — case setup, meshing, solver runs and post-processing — with an AI copilot across the whole workflow rather than bolted onto one step.

This guide takes a new user from a blank machine to a finished, verified simulation. Everything here is the real application, screen by screen.

Start here

  • 1 Installation

    Requirements, the AppImage, and automatic OpenFOAM detection. One file, no root, no dependencies.

  • 2 First launch & account

    Create an account, sign in on a second machine, and what Free gives you versus Pro.

  • 3 Tour of the interface

    The three panes, the tool rail, Case Builder, Solver Workshop, the Copilot and the mesh preview.

  • 4 Common workflows

    Open a case, generate a mesh, run the solver — plus a full worked lid-driven-cavity example, screen by screen.

The worked example

If you only read one section, make it 4.6 Worked example — lid-driven cavity at Re = 1000.

It is the standard CFD verification problem, it has a published answer, and it tells you whether a surprising result is your setup or the solver. A correct run reproduces Ghia, Ghia & Shin (1982) along the vertical centreline to well under one percent, with the primary vortex centred near (0.53, 0.56).

Why start with a benchmark

Running a case with a known answer first means every later surprise is information about your problem, not about your installation.
