Processing filters

The processing module of geos-mesh package contains filters to process meshes.

geos.mesh.processing.SplitMesh filter

SplitMesh module is a vtk filter that split cells of a mesh composed of Tetrahedra, pyramids, and hexahedra.

Filter input and output types are vtkUnstructuredGrid.

To use the filter:

from geos.mesh.processing.SplitMesh import SplitMesh

# filter inputs
input :vtkUnstructuredGrid

# instanciate the filter
filter :SplitMesh = SplitMesh()
# set input data object
filter.SetInputDataObject(input)
# do calculations
filter.Update()
# get output object
output :vtkUnstructuredGrid = filter.GetOutputDataObject(0)
class geos.mesh.processing.SplitMesh.SplitMesh[source]

Bases: VTKPythonAlgorithmBase

SplitMesh filter splits each cell using edge centers.

FillInputPortInformation(port, info)[source]

Inherited from VTKPythonAlgorithmBase::RequestInformation.

Parameters:

  • port (int) – input port

  • info (vtkInformationVector) – info

Returns:

1 if calculation successfully ended, 0 otherwise.

Return type:

int

RequestData(request, inInfoVec, outInfoVec)[source]

Inherited from VTKPythonAlgorithmBase::RequestData.

Parameters:

  • request (vtkInformation) – request

  • inInfoVec (list[vtkInformationVector]) – input objects

  • outInfoVec (vtkInformationVector) – output objects

Returns:

1 if calculation successfully ended, 0 otherwise.

Return type:

int

RequestDataObject(request, inInfoVec, outInfoVec)[source]

Inherited from VTKPythonAlgorithmBase::RequestDataObject.

Parameters:

  • request (vtkInformation) – request

  • inInfoVec (list[vtkInformationVector]) – input objects

  • outInfoVec (vtkInformationVector) – output objects

Returns:

1 if calculation successfully ended, 0 otherwise.

Return type:

int
