Data offered docs-verified: SRH-2D simulation results (read, VTK conversion, sampling and probing) · HEC-RAS 2D results from HDF files · conversion of HEC-RAS 2D mesh, boundary conditions and Manning's n to SRH-2D format · difference between simulation results · georeferenced terrain creation and manipulation · 2D-to-3D extrusion with OpenFOAM conversion via Gmsh MSH
Formats llm-inferred: VTK · HDF · GeoTIFF · Gmsh MSH · SRH-2D format
Access docs-verified: Open source, MIT licence (per ENTRY). Requires separately installed SRH-2D (via Aquaveo SMS) and/or HEC-RAS. The AI-agent workflow also requires an AI coding assistant and the pyHMT2D[ai] extras.

Use cases llm-inferred: Batch calibration runs of Manning's n across HEC-RAS 2D or SRH-2D flood models · Monte Carlo sensitivity runs on 2D hydraulic model inputs · Converting HEC-RAS 2D results to VTK for visualisation and analysis of depth and velocity · Model inter-comparison by running the same mesh in HEC-RAS 2D and SRH-2D
Audience llm-inferred: flood consultants · hydraulic modellers · hydrologists · GIS analysts · Python-literate engineers

Constraints docs-verified: Currently only Windows is supported; Linux is tested with limited support and needs the Linux versions of the hydraulic models · Supports only SRH-2D, HEC-RAS and the Backwater-1D toy model · SRH-2D and HEC-RAS must be installed separately · Developed with SMS v13.4.11 and HEC-RAS v6.6; other versions may work but are not fully tested · AI-agent workflow requires an AI coding assistant such as Claude Code, Cursor, or Gemini
