# 7.6.19.1.12. Rotation_Tensor

Syntax

  User Expression ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) = Rotation_Tensor (User_Tag = user_tag | Theta = theta | [Nx = nx] | [Ny = ny] | [Nz = nz] | [Equations = Equations…])

Scope

  Aria Material

Summary

  Rotation tensor user expression

Description

  Calculates a rotation tensor around a defined axis [nx, ny, nz] by an angle expression ‘theta’. In 2D the axis is always [0, 0, 1]
