Cylindrical Domain

Cylindrical Domain

Cylindrical Simulation Domain

Defines a cylindrical computational domain. Recommended for multi-directional wind analysis as it allows for changing wind directions without re-meshing.

Eddy3D 0.5.0.815

Input

  • Bldg
    Building geometry (Breps or Meshes). These create wall boundary conditions in the CFD mesh.
  • Terr
    Optional: Ground surface geometry. Must extend beyond domain bounds. If omitted, a flat ground is assumed.
  • Tree
    Optional: Tree/vegetation objects from Tree component. Creates porous zones for wind resistance.
  • BC
    Wind inlet conditions from ABL Flow or Uniform Flow component. Can include multiple wind directions.
  • Cell
    Base mesh cell size. Units: meters. Smaller = more accurate but slower. Typical: 5-20m. Default: 20m
  • Inner
    Size of the inner rectangular region. Units: meters. Should contain all buildings.
  • Outer
    Radius of the outer cylindrical boundary. Units: meters. Recommend: 5-6x tallest building height.
  • Hgt
    Domain height. Units: meters. Recommend: 5-6x tallest building height.
  • RadMult
    Controls radial mesh grading. Higher = more cells near center. Default: 2
  • DivX
    Additional mesh refinement in X direction. Only visible after meshing. Default: 1

Output

  • Dom
    CFD domain object for Wind Simulation component
  • Prev
    Domain boundary mesh for visualization
