SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill simplifies the execution and analysis of complex computational fluid dynamics (CFD) simulations, enabling researchers to study phenomena like turbulence and geophysical flows without deep expertise in low-level coding.

Core Features & Use Cases

  • CFD Solvers: Offers solvers for Navier-Stokes (2D/3D), stratified flows, and shallow water equations.
  • High-Performance: Utilizes pseudospectral methods with FFT and supports MPI for parallel computing.
  • Use Case: A climate scientist needs to simulate atmospheric stratification. They can use the ns2d.strat solver to model density-driven flows, configure parameters like Brunt-Väisälä frequency, and analyze the resulting buoyancy patterns.

Quick Start

Use the fluidsim skill to run a 2D Navier-Stokes simulation with noise initialization and save results every 1.0 time units.
