group_unknown_names()

tarch.plotter.api.output.VTUUnstructuredGrid.group_unknown_names

(

names

)

Group the names of the unknowns into the arrays we write.

A name v[i] belongs to the vector v, all other names are scalars. Returns a list of (array name, list of indices of the unknowns), in the order in which the arrays first show up, e.g. ["p", "v[0]", "v[1]"] yields [("p", [0]), ("v", [1, 2])].

name_unknowns()

tarch.plotter.api.output.VTUUnstructuredGrid.name_unknowns	(		grid,
			description,
			unknowns,
			is_data_associated_to_cell,
			split_unknowns
	)

Label the unknowns of a grid with their symbolic names.

If the description of the unknowns holds one name per unknown (

See also

unknown_names_from_description()), we name the components of the data array accordingly, plus the trailing subdomain component. Paraview then offers the names when you colour by the array. Otherwise, we leave the grid alone.

split_unknowns: Boolean If set, we additionally add one array per variable, so filters such as Paraview's Calculator or Contour can address it by name. A scalar becomes an array with one component. The entries v[0], v[1], ... of a variable with multiplicity become one vector array v. As Paraview only treats arrays with three components as vectors, e.g. for glyphs, we pad a vector with two entries with a zero.
