2.3.3.3.136. NXphase

Status:

base class (contribution), extends NXobject

Description:

Base class to describe a (thermodynamic) phase as a component of a material. ...

Base class to describe a (thermodynamic) phase as a component of a material.

Instances of phases can be crystalline.

Symbols:

No symbol table

Groups cited:

NXatom, NXunit_cell

Structure:

identifier: (optional) NX_INT {units=NX_UNITLESS}

Identifier for each phase. ...

Identifier for each phase.

The value 0 is reserved for the unknown phase that represents the null-model (no sufficiently significant information available). In other words, the phase_name is n/a aka notIndexed.

The identifier_phase value should match with the integer suffix of the group name which represents that instance in a NeXus/HDF5 file, i.e. if three phases were used e.g. 0, 1, and 2, three instances of NXphase named phase0, phase1, and phase2 should be stored in that HDF5 file.

name: (optional) NX_CHAR

Given name as an alias for identifying this phase. ...

Given name as an alias for identifying this phase.

If the identifier_phase is 0 and one would like to use the field name, the value should be n/a or notIndexed.

UNIT_CELL: (optional) NXunit_cell

ATOM: (optional) NXatom
