Check these points before you install SpectraSim. Everything below applies to the current version.
| Requirement | Value |
|---|---|
| Operating system | Windows 10 or Windows 11, 64-bit |
| Memory (RAM) | 16 GB recommended |
| Disk, program and flow solver | about 5 GB |
| Disk, runs | 20 GB or more advised |
| Processor | [MISSING M28 — recommended CPU (cores)] |
| Rights | administrator rights once, for the installation |
| Internet | not needed — the program works fully offline |
Check your Windows version
SpectraSim runs on Windows 10 and Windows 11, 64-bit, only. There is no version for macOS or Linux. Open Settings → System → About and check that System type reads “64-bit operating system”.
Check memory for acoustic sweeps
16 GB of RAM is recommended. Acoustic frequency sweeps of large models use several GB per worker, so more memory lets more frequencies run side by side. Small models and flow-only runs need less.
Check disk space for the program and your runs
- Program and flow solver: about 5 GB.
- Runs: 20 GB or more is advised. A large muffler run with its solution can take several GB.
The runs go to C:\SpectraSim\runs\ by default. You can move the runs folder later in File → Settings, for example to a larger data drive.
Check the processor
Recommended processor: [MISSING M28 — recommended CPU (cores)]
Get administrator rights for the installation
Administrator rights are needed once, for the installation. The program goes to C:\SpectraSim\ — the flow solver requires a short folder name — and Microsoft MPI is installed if it is missing. Day-to-day work does not need administrator rights.
What you do not need
- No internet connection. SpectraSim never connects to the internet: no telemetry and no online activation. Licences are offline files.
- No separate flow solver. The OpenFOAM flow solver is installed with SpectraSim, unmodified, with its licence.
- No ParaView. 3-D results are shown inside SpectraSim; ParaView is optional, for opening the VTK export.
