Detailed Description

Legacy VTK file format writer.

Original source file foamToVTK.C

- handles volScalar, volVector, pointScalar, pointVector, surfaceScalar fields.

• mesh topo changes.
• both ascii and binary.
• single time step writing.
• write subset only.
• automatic decomposition of cells; polygons on boundary undecomposed since handled by vtk.

Usage

• foamToVTK [OPTION]

Parameters

-ascii	Write VTK data in ASCII format instead of binary.
-mesh	<name> Use a different mesh name (instead of -region)
-fields	<fields> Convert selected fields only. For example, -fields "( p T U )" The quoting is required to avoid shell expansions and to pass the information as a single argument.
-surfaceFields	Write surfaceScalarFields (e.g., phi)
-cellSet	<name>
-faceSet	<name>
-pointSet	<name> Restrict conversion to the cellSet, faceSet or pointSet.
-nearCellValue	Output cell value on patches instead of patch value itself
-noInternal	Do not generate file for mesh, only for patches
-noPointValues	No pointFields
-noFaceZones	No faceZones
-noLinks	(in parallel) do not link processor files to master
poly	write polyhedral cells without tet/pyramid decomposition
-allPatches	Combine all patches into a single file
-excludePatches	<patchNames> Specify patches (wildcards) to exclude. For example, -excludePatches '( inlet_1 inlet_2 "proc.*")' The quoting is required to avoid shell expansions and to pass the information as a single argument. The double quotes denote a regular expression.
-useTimeName	use the time index in the VTK file name instead of the time index

Note

mesh subset is handled by vtkMesh. Slight inconsistency in interpolation: on the internal field it interpolates the whole volField to the whole-mesh pointField and then selects only those values it needs for the subMesh (using the fvMeshSubset cellMap(), pointMap() functions). For the patches however it uses the fvMeshSubset.interpolate function to directly interpolate the whole-mesh values onto the subset patch.

new file format:
no automatic timestep recognition. However can have .pvd file format which refers to time simulation if XML *.vtu files are available:

      <?xml version="1.0"?>
      <VTKFile type="Collection"
           version="0.1"
           byte_order="LittleEndian"
           compressor="vtkZLibDataCompressor">
        <Collection>
          <DataSet timestep="50" file="pitzDaily_2.vtu"/>

          <DataSet timestep="500" file="pitzDaily_11.vtu"/>
        </Collection>
      </VTKFile>
