project-overview

A set of project notes for pyHMT2D, a Python package that automates two-dimensional water-flow simulations and processes their results.

In plain words
What is it for?
Use it when working on model automation, calibration, batch or Monte Carlo simulations, result conversion, mesh and boundary-condition conversion, or visualization with pyHMT2D.
Why use it?
It gives the coding assistant the project's structure, supported models, and expected workflows before it changes or explains the code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

project-overview scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

pyHMT2D Project Overview

pyHMT2D is a Python package for controlling and automating 2D hydraulic modeling, with support for pre- and post-processing simulation results. The package currently supports:

  • SRH-2D (USBR)
  • HEC-RAS (USACE)
  • Backwater-1D (demonstration model)

Key Components

The main package structure is organized as follows:

Key Features

  1. Model Control and Automation

    • Batch simulations
    • Model calibration
    • Monte-Carlo simulations

  2. Data Processing

    • Reading model results into NumPy arrays
    • Converting results to VTK format
    • Sampling and probing simulation results

  3. Model Interoperability

    • Converting between SRH-2D and HEC-RAS formats
    • Mesh and boundary condition conversion
    • Result comparison tools

  4. Visualization and Analysis

    • VTK-based visualization
    • Result analysis tools
    • Terrain data manipulation

Getting Started

  1. Installation:

    pip install pyHMT2D

  2. Basic Usage:

    import pyHMT2D

  3. Documentation:

    • See docs/ for detailed documentation
    • Check examples/ for usage examples

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

project-overview is a cursor rule published in the GitHub repository psu-efd/pyHMT2D (128 stars, last pushed 23d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 530 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
