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{}
    ...
}
