import_strain{ }¶

Calling sequence

strain{ import_strain{ } }

Properties

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

Dependencies

import{ } must be defined.
linear_solver{ } and residual_strain are not allowed if this group is defined.
Exactly one out of no_strain{ }, pseudomorphic_strain{ }, minimized_strain{ }, and import_strain{ } must be defined.
One of pseudomorphic_strain{ }, minimized_strain{ }, and import_strain{ } must be present to allow using output_hydrostatic_strain{ }, output_strain_tensor{ }, output_piezo_constants{ }, output_second_order_piezo_constants{ }.

Functionality

Controls importing strain tensor elements to the simulation from an external file.

Example

strain{
    import_strain{...}
}

import{...}

Nested keywords

import_from¶

Calling sequence

strain{ import_strain{ import_from } }

Properties

usage: \(\mathrm{\textcolor{WildStrawberry}{required\;within\;the\;group}}\)
type: \(\mathrm{character\;string}\)

Functionality

Reference to imported data in import{ }.

The data being imported must have exactly 6 components. The expected order of strain tensor components is: \(\varepsilon_{xx}\ \varepsilon_{yy}\ \varepsilon_{zz}\ \varepsilon_{xy}\ \varepsilon_{xz}\ \varepsilon_{yz}\)

Example

strain{
    import_strain{
        import_from = "strain_import"
    }
}

import{
    file{
        name = "strain_import"
        ...
    }
}

coordinate_system¶

Calling sequence

strain{ import_strain{ coordinate_system } }

Properties

usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)
type: \(\mathrm{choice}\)
choices: crystal; simulation
default: simulation

Functionality

The imported strain tensor is with respect to the simulation or crystal coordinate system (optional parameter).

Example

strain{
    import_strain{
        import_from = "strain_import"
        coordinate_system = "simulation"
    }
}

import{
    file{
        name = "strain_import"
        ...
    }
}
