import_strain{ }

Calling sequence

strain{ import_strain{ } }

Properties

• usage: $\mathrm{conditional}$

• items: 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{...}

import_from

Calling sequence

strain{ import_strain{ import_from } }

Properties

• usage: $\mathrm{required}$

• type: 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: ${\epsilon }_{xx}{\epsilon }_{yy}{\epsilon }_{zz}{\epsilon }_{xy}{\epsilon }_{xz}{\epsilon }_{yz}$

Example

strain{
    import_strain{
        import_from = "strain_import"
    }
}

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

coordinate_system

Calling sequence

strain{ import_strain{ coordinate_system } }

Properties

• usage: $\mathrm{optional}$

• type: choice

• values: crystal or 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"
        ...
    }
}
