Detailed Description

A surface formed by the iso value. After "Regularised Marching Tetrahedra: improved iso-surface extraction", G.M. Treece, R.W. Prager and A.H. Gee.

Note:

  • does tets without using cell centres/cell values. Not tested.
  • regularisation can create duplicate triangles/non-manifold surfaces. Current handling of those is bit ad-hoc for now and not perfect.
  • regularisation does not do boundary points so as to preserve the boundary perfectly.
  • uses geometric merge with fraction of bounding box as distance.
  • triangles can be between two cell centres so constant sampling does not make sense.
  • on empty patches behaves like zero gradient.
  • does not do 2D correctly, creates non-flat iso surface.
  • on processor boundaries might two overlapping (identical) triangles (one from either side)

The handling on coupled patches is a bit complex. All fields (values and coordinates) get rewritten so

  • empty patches get zerogradient (value) and facecentre (coordinates)
  • separated processor patch faces get interpolate (value) and facecentre (coordinates). (this is already the default for cyclics)
  • non-separated processor patch faces keep opposite value and cell centre

Now the triangle generation on non-separated processor patch faces can use the neighbouring value. Any separated processor face or cyclic face gets handled just like any boundary face.

◆ isoSurfacePoint()

isoSurfacePoint ( const volScalarField cellValues,
const scalarField pointValues,
const scalar  iso,
const isoSurfaceParams params = isoSurfaceParams(),
const bitSet ignoreCells = bitSet() 
)

Construct from cell values and point values.

Uses boundaryField for boundary values. Holds reference to cellIsoVals and pointIsoVals.

Control parameters include

  • bounds optional bounding box for trimming
  • mergeTol fraction of mesh bounding box for merging points
Parameters
