Bookmark or Share- Thermodynamics and Kinetics - Kawinkawin supports three different methods to calculate the driving force. Approximate # The approximate method assumes that the composition of a newly nucleated precipitate is near the equilibrium composition.
- Shape factors - KawinIn defining the precipitate shape, three terms will be used: the long axis (l), the short axis (r) and the equivalent spherical radius (R). Additionally, for ellipsoids, the eccentricity can be defined (which simplifies some of the following equations).
- Kawin - Multicomponent Precipitation SimulationsKawin is a free and open source Python library for performing kinetic simulations using the Kampmann-Wagner Numerical (KWN) model.
- Kampmann-Wagner Numerical Model - Kawinkawin relies on classical nucleation and growth theories to model precipitation behavior in alloys. There are several ways to model precipitation behavior using these theories. The Langer-Schwartz (LS) model predicts the evolution of the mean radius of particles in near critical fluids.
- Diffusion Modeling - KawinInstructions on installing developmental versions of kawin can be found here. Although kawin was originally designed for precipitation modeling, the calculation of mobility and diffusivity creates a pathway to implemenet and perform 1-dimensional diffusion simulations.
