Surface Refinement

Surface Refinement#

Surface refinement provides direct control over the maximum permissible size of surface mesh elements, ensuring adequate resolution of geometric features and maintaining mesh quality across surfaces.

Available Options#

Option

Description

Max edge length

Maximum allowed length of surface mesh edges

Assigned surfaces

Target surfaces for refinement application

Detailed Descriptions#

Max Edge Length#

Defines the upper bound for surface mesh element size.

  • Required

  • Example: 0.05 m

Note: Should be chosen based on smallest geometric feature requiring resolution.

Assigned surfaces#

Specifies the geometric surfaces where refinement will be applied.

  • Required

Notes:

  • Must reference valid surface entities in the geometry.

  • Assign the boundaries by selecting from the list using the + button or select graphically in the viewer region.

❓ Frequently Asked Questions

  • What happens if surface refinements overlap?

    The finest (smallest) edge length will be applied in overlapping regions.

Python API:

import flow360 as fl

# Surface refinement for wing
surface_ref = fl.SurfaceRefinement(
    name="wing_surface",
    faces=[wing_surface],
    max_edge_length=0.05 * fl.u.m
)

# Surface refinement for complex geometry
complex_surface_ref = fl.SurfaceRefinement(
    name="complex_surface",
    faces=[complex_surface],
    max_edge_length=0.02 * fl.u.m  # Smaller value for complex features
)
