Summary

The algorithm loads an Environment into the instrument of a workspace at the sample.

Properties

Name Direction Type Default Description
InputWorkspace Input MatrixWorkspace Mandatory The name of the workspace containing the instrument to add the Environment
Filename Input string Mandatory The path name of the file containing the Environment. Allowed extensions: [‘.stl’]
OutputWorkspace Output MatrixWorkspace Mandatory The name of the workspace that will contain the loaded Environment of the sample
EnvironmentName Input string Environment  
Add Input boolean False  
TranslationVector Input dbl list 0,0,0 Vector by which to translate the loaded environment
RotationMatrix Input dbl list 1,0,0,0,1,0,1,0,0 Rotation Matrix in format x1,x2,x3,y1,y2,y3,z1,z2,z3
SetMaterial Input boolean False  
ChemicalFormula Input string   The chemical formula, see examples in documentation
AtomicNumber Input number 0 The atomic number
MassNumber Input number 0 Mass number if ion (use 0 for default mass sensity)
SampleNumberDensity Input number Optional This number density of the sample in number of atoms per cubic angstrom will be used instead of calculated
ZParameter Input number Optional Number of formula units in unit cell
UnitCellVolume Input number Optional Unit cell volume in Angstoms^3. Will be calculated from the OrientedLattice if not supplied.
CoherentXSection Input number Optional Optional: This coherent cross-section for the sample material in barns will be used instead of tabulated
IncoherentXSection Input number Optional Optional: This incoherent cross-section for the sample material in barns will be used instead of tabulated
AttenuationXSection Input number Optional Optional: This absorption cross-section for the sample material in barns will be used instead of tabulated
ScatteringXSection Input number Optional Optional: This total scattering cross-section (coherent + incoherent) for the sample material in barns will be used instead of tabulated
SampleMassDensity Input number Optional Measured mass density in g/cubic cm of the sample to be used to calculate the number density.
NumberDensityUnit Input string Atoms Choose which units SampleNumberDensity referes to. Allowed values: [‘Atoms’, ‘Formula Units’]

Description

Loads an environment into the sample of a workspace, either replacing the current environment, or adding to it. you may also set a material for the environment to be loaded, this follows the same inputs as SetSampleMaterial v1.

The following types of input file are supported:

  • *.stl stereolithography https://en.wikipedia.org/wiki/STL_(file_format) This is a file format consisting of a list of faces specified by their vertex coordinates. The file may be in ASCII or Binary format, and all the faces must be triangular. The normals are ignored, but the vertices must be in the order required by the standard (counter-clockwise when viewed from outside).
