output_strain_tensor{ }¶

Calling sequence

strain{ output_strain_tensor{ } }

Properties

usage: \(\mathrm{\textcolor{Dandelion}{conditional}}\)
items: \(\mathrm{maximum\;1}\)

Dependencies

This keyword is allowed if one of pseudomorphic_strain{ }, minimized_strain{ }, and import_strain{ } is defined.

Functionality

output (symmetric) strain tensor : \(\varepsilon_{ij} = (u_{ij} + u_{ji})/2\) [dimensionless]

Example

strain{
    output_strain_tensor{}
    pseudomorphic_strain{}
}

Nested keywords

crystal_system¶

Calling sequence

strain{ output_strain_tensor{ crystal_system } }

Properties

usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)
type: \(\mathrm{choice}\)
choices: yes; no
default: no

Functionality

output strain tensor in crystal coordinate system

Example

strain{
    output_strain_tensor{
        crystal_system = yes
    }
    pseudomorphic_strain{}
}

simulation_system¶

Calling sequence

strain{ output_strain_tensor{ simulation_system } }

Properties

usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)
type: \(\mathrm{choice}\)
choices: yes; no
default: yes

Functionality

output strain tensor in simulation coordinate system (useful if simulation coordinate system differs from crystal coordinate system)

Note

The ordering of the strain tensor components is: \(\varepsilon_{xx},\ \varepsilon_{yy},\ \varepsilon_{zz},\ \varepsilon_{xy},\ \varepsilon_{xz},\ \varepsilon_{yz}\)

Example

strain{
    output_strain_tensor{
        simulation_system = no
    }
    pseudomorphic_strain{}
}

boxes¶

Calling sequence

strain{ output_strain_tensor{ boxes } }

Properties

usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)
type: \(\mathrm{choice}\)
choices: yes; no
default: no

Functionality

For each grid point, in 1D two points are printed out to mimic abrupt discontinuities at interfaces (in 2D four points, in 3D eight points)

Example

strain{
    output_strain_tensor{
        boxes = yes
    }
    pseudomorphic_strain{}
}
