output_strain_tensor{ }

Calling sequence

strain{ output_strain_tensor{ } }

Properties

• usage: $\mathrm{conditional}$

• items: maximum 1

Dependencies

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

Functionality

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

Example

strain{
    output_strain_tensor{}
    pseudomorphic_strain{}
}

Nested keywords

crystal_system

Calling sequence

strain{ output_strain_tensor{ crystal_system } }

Properties

• usage: $\mathrm{optional}$

• type: choice

• values: yes or 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: $\mathrm{optional}$

• type: choice

• values: yes or 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: ${\epsilon }_{xx},{\epsilon }_{yy},{\epsilon }_{zz},{\epsilon }_{xy},{\epsilon }_{xz},{\epsilon }_{yz}$

Example

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

boxes

Calling sequence

strain{ output_strain_tensor{ boxes } }

Properties

• usage: $\mathrm{optional}$

• type: choice

• values: yes or 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{}
}
