growth_direction¶
- Calling sequence
strain{ growth_direction }
- Properties
using: \(\mathrm{\textcolor{Dandelion}{conditional}}\)
type: \(\mathrm{vector\;of\;3\;integers}\)
values: no constraints
default:
[1.0, 0.0, 0.0]
unit: \(\mathrm{-}\)
- Dependencies
This keyword is not allowed if simulate1D{ } is defined.
- 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{} ... }
