Purpose

Apply local refinement within a box or cylinder, or define a volume zone for supported models.

Steps

  1. Open Volume refinement | Zones and choose the required type and Box or Cylinder shape.

    Volume refinement controls

  2. For a box, enter two diagonal corner points. For a cylinder, enter the center, radius point, and height point.
  3. For refinement, set the local cell size. Use Preview, Add to List, then Apply and Close. Right-click a listed entry to remove it.

Inputs and units

Input or valueMeaningUnits
Coordinates / lengthsUse the unit displayed beside the field.m (SI); ft (Imperial)
Local cell sizeTarget spacing inside the refinement volume.m (SI); ft (Imperial)
Zone typeRefinement, Porous, or Rotating, as available.No physical units

Limitations

  • A refinement volume changes mesh spacing; porous and rotating zones need their corresponding physical properties configured in Setup. Use positive dimensions and a nonzero cylinder radius and height.
