HASEonGPU.MeshTopology

class HASEonGPU.MeshTopology(points, trianglePointIndices, levels=None, thickness=None, metadata=<factory>)

Bases: object

Triangular base mesh extruded through z levels into wedge prisms.

points are transverse (x, y) coordinates. trianglePointIndices connect those points into the 2D base mesh. levels and thickness describe the z sampling used by betaCells and betaVolume.

Parameters:

• points (ndarray)

• trianglePointIndices (ndarray)

• levels (int | None)

• thickness (float | None)

• metadata (dict)

points: ndarray

Transverse coordinates with shape (numberOfPoints, 2).

trianglePointIndices: ndarray

Triangle vertex indices with shape (numberOfTriangles, 3).

levels: int | None = None

Number of z sample planes; at least two when simulation data is used.

thickness: float | None = None

Distance between adjacent z sample planes.

metadata: dict

Importer or construction metadata kept for tooling and round-trips.

classmethod fromPoints(points, numberOfLevels=None)

Delaunay-triangulate transverse points into a MeshTopology.

classmethod fromGrid(grid)

Construct topology from a regular Grid helper.

classmethod fromGmsh(gmsh, *, numberOfLevels=None, thickness=None)

Import a planar gmsh triangle mesh and attach z sampling.

classmethod fromFile(filename, format=None, numberOfLevels=None, thickness=None)

Load supported mesh formats: legacy VTK, planar STL, or gmsh.

numberOfLevels(levels)

Set the number of z sample planes and return self.

withThickness(thickness)

Set the spacing between adjacent z levels and return self.

levelCoordinates()

Return z coordinates for every level as 0, thickness, ....

pointIndexAt(x, y, *, tol=1e-12)

Return the topology point index for a transverse coordinate.

levelIndexAt(z, *, tol=1e-12)

Return the z-level index for a physical z coordinate.

betaCellIndexAt(x, y, z, *, tol=1e-12, flat=False)

Return the betaCells index for a physical (x, y, z) point.

property numberOfTriangles

Number of base triangles, and therefore prisms per z interval.

property numberOfPoints

Number of transverse sample points per z level.

property numberOfPrisms

Total number of wedge prisms in the extruded mesh.

asGainMedium()

Wrap this topology in an empty GainMedium.
