Functionality
Defines a normal vector to a substrate surface, corresponding to the growth direction, for a pseudomorphic strain model. It is defined in crystal coordinate system. It can be specified in a 2D and 3D simulations, but not in a 1D simulation as the crystal direction along the x-axis is always chosen in this case.
Example
strain{
growth_direction = [1, 1, 0]
pseudomorphic_strain{}
}
global{
simulate2D{}
...
}
