Functionality

Residuals strain in the substrate \(\eta\) scales lattice parameter of the substrate (only for the purpose of strain computation) according to the formula \(a_{\eta,s}=(1+\eta)\cdot a_{0,s}\), where \(a_{0,s}\) is the (unstrained) lattice parameter of the substrate and \(a_{\eta,s}\) the modified (strained) lattice parameter of the substrate. The latter one represents the substrate during evaluation of the strain tensor.

Example
strain{
    residual_strain = 0.2
    pseudomorphic_strain{}
}
