Boundary conditions and interfaces

These pages explain how Vanellus applies flow and thermal conditions to domain and component surfaces.

• Boundary placement and defaults describes placement, overrides, and the default behavior of interfaces between materials.
• Flow boundary conditions explains the velocity, pressure, temperature, and turbulence conditions applied by each inlet and outlet.
• Thermal boundary conditions explains fixed temperature, heat flux, far-field radiation, and adiabatic behavior.
• Fan and linked-fan boundaries explains how exterior and internal fan boundaries couple pressure, flow, and temperature.

For configuration steps, use the Geometry and mesh and Flow and heat transfer How-to guides.
