OpenMC on SoftFission

OpenMC is the first code supported on SoftFission. This page gives a short overview of the code, explains how it fits the SoftFission workflow, and includes license and attribution information. It may later also become the home for starter examples and reusable project templates.

Code type
Open source
OpenMC is an openly developed scientific codebase.
Method
Monte Carlo
Used for neutron transport and related reactor-physics studies.
SoftFission fit
Strong
File-based inputs and batch execution fit the private compute workflow well.

What OpenMC is

A short introduction for users who are new to the code.

OpenMC is a Monte Carlo particle transport code used in reactor-physics and nuclear-engineering workflows. In practice, users prepare model inputs, run calculations, and inspect results such as tallies and derived quantities.

SoftFission does not try to replace the official OpenMC documentation. Instead, it provides a more structured environment for preparing inputs, reserving compute time, launching runs, and storing results in a personal workspace.

Why SoftFission starts with OpenMC

The first supported code should fit the platform’s operational model.

OpenMC projects are naturally organized around files, inputs, and outputs, which fits the SoftFission workspace model.
Batch runs map well to a personal on-demand compute node with reserved duration and scheduler-managed jobs.
Keeping project files, run snapshots, and outputs together supports more reproducible technical work.

Workflow on SoftFission

The typical path from project creation to results.

1. Create project
Start an OpenMC project in your workspace.
2. Prepare inputs
Upload or edit XML inputs and related files.
3. Reserve compute
Create your personal compute node with reserved duration.
4. Submit run
Launch the calculation and track status in the project.
5. Inspect results
Open run files, logs, and generated outputs.
6. Reuse and export
Download results and build on previous project inputs.

License and attribution

OpenMC is third-party open source software used within the SoftFission workflow.

OpenMC is not owned by SoftFission. It is developed by its respective authors and contributors and is made available under its own open source license.

SoftFission provides hosted workflow support, project organization, and compute infrastructure for running OpenMC, but does not claim ownership of the OpenMC software.

Examples and starter models

This section can later become the home for reusable templates and benchmark-style starter cases.

Examples will appear here later

A future version of this page can include starter OpenMC projects, example inputs, and reusable model templates.
