orcaflex-modeling
Setup, configure, and run OrcaFlex hydrodynamic simulations using the universal runner. Use for marine/offshore analysis including static analysis, dynamic simulations, mooring analysis, and batch processing of OrcaFlex models.
Best use case
orcaflex-modeling is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Setup, configure, and run OrcaFlex hydrodynamic simulations using the universal runner. Use for marine/offshore analysis including static analysis, dynamic simulations, mooring analysis, and batch processing of OrcaFlex models.
Teams using orcaflex-modeling should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.
