Abstract
This app calculates the equilibrium shape of a precipitate (particle) that has a misfit strain relative to the matrix it sits in. The calculation is performed using the phase field method using the PRISMS-PF framework (https://prisms-center.github.io/phaseField/). The app automatically measures the dimensions of the precipitate as well as the volume fraction. Users can see how these values change as they modify the components of the misfit strain, the elastic constants for the matrix and precipitate, and the interfacial energy.
