Download
A small installer that fetches the rest.
The setup program is a couple of megabytes. It shows the terms, downloads the application from our servers, verifies its SHA-256, and offers the solved example scenes as an optional extra. Running inWaves needs an account and a license; a 30-day trial counts.
Already have an account? The portal lists every build with its checksum and release notes: portal downloads.
What the setup does
- Terms of use. The EULA is shown and must be accepted before anything is downloaded.
- gmsh. inWaves builds volume meshes with gmsh, a separate free program. Its licence (GPLv2+) means we do not ship it, so the setup opens its download page and then checks that it can find it. You can install it later; everything except volume meshing works without it.
- The application. Downloaded from our servers and checked against a SHA-256 that is built into the setup. A truncated or tampered download is refused, not installed.
- Example scenes (optional). Solved projects, over a gigabyte in total, so they are a separate download. Skip them here and the welcome screen can fetch them later, at any time.
System requirements
| Operating system | Windows 10 or 11, 64-bit (x64). No macOS or Linux build. |
|---|---|
| Memory | 16 GB RAM recommended. The largest example scene wants 4 GB by itself. |
| gmsh | Required for volume meshing, installed separately (GPLv2+, so it is not shipped with inWaves). The setup links to it and checks for it. |
| GPU (optional) | NVIDIA GPU with CUDA for flow-solver acceleration. Not required; without one the same build solves everything on the processor. |
| Network | Internet connection at application launch for license activation/validation. Solving is fully local. |
Verify what you run
The setup verifies the application package against a checksum built into it, so a bad download cannot reach your disk. The setup itself is published with a SHA-256 checksum next to it, and the portal shows one for every build. Compare before you run it:
PS> Get-FileHash .\inwaves-setup.exe -Algorithm SHA256If the hash does not match the portal's value, do not run the installer. Download again and tell us.
About the Windows SmartScreen warning
Our installers are not code-signed yet, so Windows SmartScreen will warn that the publisher is unknown. Verify the SHA-256 checksum against your portal first, then choose More info → Run anyway. Code signing is on the roadmap; until then the checksum from your authenticated portal session is your integrity guarantee.
