Parameters

name	description	type
filter_expression	elements for which this expression is true are filtered out, for supported symbols see selection lists	String
filter_type	on what to filter (Ghost, Elements, Vertices)	Int
supported_variables	variables available for use in filter expression (cellDiameter, datavalue, dimensionality, edgeLength, elem, numFaces, numVertices, surface, type, volume, x_center, x_max, x_min, y_center, y_max, y_min, z_center, z_max, z_min)	Int
supported_constants	constants available for use in filter expression (BAR, HEXA, HEXAHEDRON, LINE, NONE, PLG, PLH, POINT, POLYGON, POLYHEDRON, POLYLINE, PRISM, PT, PYR, PYRAMID, QUAD, TETRA, TETRAHEDRON, TRI, TRIANGLE)	Int

Supported System Parameters

name	description	type
_openmp_threads	number of OpenMP threads (0: system default)	Int
_benchmark	show timing information	Int
_concurrency	number of tasks to keep in flight per MPI rank (-1: #cores/2)	Int
_cache_mode	input object caching (CacheNone, CacheDeleteEarly, CacheDeleteLate, CacheByName)	Int
_prioritize_visible	prioritize currently visible timestep	Int
_validate_objects	validate data objects before sending to port (Disable, Quick, Thorough)	Int

The meaning of these parameters is described in more detail in the System Parameters documentation.

The filter_expression is parsed with ExprTK, and so the operations and functions described in SECTION 08 - BUILT-IN OPERATIONS & FUNCTIONS of this document can be used. The available variables and constants are listed in the parameters supported_variables and supported_constants respectively.
