Frequently asked

No. The Linux compute binaries published by the Hydrologic Engineering Center are bundled inside the image, and HEC-RAS itself is free software. No Windows desktop, no virtual machine, no per seat licence.

If it is a 2D unsteady HEC-RAS project with a plan, a geometry, and named boundary condition lines, yes. The scanner reads the project and geometry files directly, so there is no conversion step. Both SI and English unit projects work.

Nowhere you did not send it. Running locally, the model folder is mounted read only and results are written to your own disk. Cloud storage is opt in, and credentials come from the container environment or an attached IAM role, never from the web page.

Yes. Set a repeat interval and the pipeline re-fetches boundary conditions, re-runs the solver, and republishes on its own. Threshold rules email a decision maker when a condition crosses from safe to exceeded, and a read only live view can be shared.

That depends on your mesh, your time step, and the cores you give the container, exactly as on a desktop. The Run tab lets you pick the thread count, so the same model finishes faster on a bigger machine.

Yes. The live data feeds need network access, but the model scanner, the solver, the mapping, and the validation all work on an air gapped machine with boundary conditions supplied from files.

Pull the newest image tag. The application shows a notice when a newer version is published, and every release is documented.
