Fluid Dynamics
This simulation is designed for learning and visualization.
This simulation uses an educational 2D flow model.
Flow is visualized with animated dashed streamlines generated from a simplified 2D velocity field.
The dashed motion follows the local velocity magnitude of the field, so faster regions move faster on screen. The dashes are a visualization of flow direction and relative speed; they are not particles, molecules, density, or mass.
Pressure, fast-flow, and wake indicators are educational guides derived from the simplified velocity field, local speed sampling, and main flow direction.
This is not a full CFD solver and does not solve the Navier-Stokes equations directly.
Assumptions:
Model basis
