What problem does it solve? Setting up and running TELEMAC-MASCARET hydrodynamic simulations requires deep operational knowledge of SELAFIN binary formats, CAS steering files, unit conventions, and failure modes that are scattered across manuals and source code. This Skill packages that expertise so an AI agent can prepare inputs, execute the telemac2d solver, parse results, and recover from known errors without inventing approximations. ## Core Features & Use Cases - End-to-end pipeline tooling: Four Python tools convert meteorological/tidal forcing, interpolate bathymetry onto meshes, execute the TELEMAC binary, and parse SELAFIN results into CSV time series. - Diagnostic recovery: 18 symptom-diagnosis-remedy triplets cover known failure modes such as Manning/Strickler friction confusion, bathymetry sign inversion, WGS84 coordinate traps, and CFL violations. - Validation against cited standards: Outputs like water depth H and free surface S are graded against literature-cited RMSE and bias bands rather than intuition. - Use Case: A coastal engineer asks the agent to model tidal flooding in an estuary; the Skill guides mesh preparation, forcing conversion, telemac2d execution, and validation of water levels against gauge observations. ## Quick Start Ask the agent to run the TELEMAC-MASCARET bump test case and parse the resulting SELAFIN output into a CSV time series of water depth and velocity.
