strain-calculation-models

More information for the different ways of how to include strain into the calculation can be found at the keyword $simulation-flow-control.

Specify whether to calculate strain pseudomorphic (appropriate in 1D and for homogeneous layers only -> homogeneous-strain), use the strain-minimization option (2D/3D) to minimize the elastic energy, read it from input file or don't use strain at all. If using homogeneous-strain, you will have to supply a substrate material that must be specified under the keyword $domain-coordinates. If using strain-minimization you must include the keyword $strain-minimization-model to specify substrate and boundary conditions. You should be careful when using  homogeneous-strain in 2D or 3D simulations (only appropriate for certain types of layers).
