Draft. This manual is new and still being checked against the software as it is verified. Some pages will change. If something here does not match what you see, the software is right — tell us and we will fix the page.

Getting started

The shortest path from nothing installed to a result you can read. No theory — that is Concepts, and it will make more sense once you have run something.
Installation System requirements, where things go, and how to check the install actually worked
Licensing and activation The free tier’s limits, activating a paid licence, working offline, moving machines
Your first simulation A worked example from opening the application to a PDF report

If you read one page

Section titled “If you read one page”

Your first simulation. It uses one of the nine bundled examples, so there is nothing to import and nothing to draw, and it goes end to end — mesh, run, post-process, report. The hull it follows still has to be meshed and solved, which takes a few minutes; the square duct meshes in seconds and runs in about one, if you would rather see the whole loop first.

Two ideas from it are worth carrying into everything else:

A case is one body and any number of studies of it. The geometry belongs to the case; the mesh, the physics and the run belong to a simulation inside it. That is what lets you compare two meshes or two turbulence models on the same body without copying anything.

The application writes an ordinary OpenFOAM case. Nothing is hidden. If you know OpenFOAM you can read every file it produces; if you do not, you never have to. Case directory layout shows exactly what lands on disk, so you can check that claim rather than take it.

Starting from your own geometry instead

Section titled “Starting from your own geometry instead”

New case on the home screen opens the Create Simulation wizard, which asks what you are analysing rather than which solver to use.

The Create Simulation dialog: an Analysis type list on the left, and a grid of families — Fluid dynamics, Structural, Coupled, Thermal, Electromagnetics, Acoustics, Shape optimisation, Explicit dynamics — with Coupled multiphysics and Studies and optimisation marked PLANNED.

Import STEP geometry picks up from there.
