Fluidsim

The fluidsim skill enables AI agents to perform computational fluid dynamics (CFD) simulations directly within their environment. It allows users to define geometry, set boundary conditions, and execute physics-based flow analysis without external software dependencies.

When to use it

• Analyze airflow patterns around custom 3D objects for aerodynamic optimization.
• Simulate heat transfer and fluid mixing in chemical engineering processes.
• Validate structural integrity of designs by modeling stress under fluid pressure loads.
• Rapidly prototype hydrodynamic behaviors for marine or automotive applications.

Key capabilities

• Generates meshed computational grids for complex geometries automatically.
• Solves Navier-Stokes equations to predict velocity, pressure, and temperature fields.
• Supports various boundary conditions including inlet, outlet, walls, and symmetry planes.
• Visualizes simulation results through vector plots, contour maps, and streamlines.

Example prompts

• "Run a steady-state CFD simulation on this cylinder shape with air flowing at 20 m/s."
• "Set up a transient fluid dynamics model to observe how dye disperses in a stirred tank."
• "Calculate the drag coefficient for this wing profile by simulating airflow at Mach 0.8."

Tips & gotchas

Ensure your input geometry is watertight and properly closed before initiating a simulation, as gaps can cause solver errors. For highly turbulent flows, specify appropriate turbulence models (e.g., k-epsilon or k-omega) to improve accuracy.
