ppiclF is a parallel particle-in-cell library written in Fortran. Applications of ppilcF include element-based particle-in-cell simulations, such as Euler-Lagrange mutliphase flow simulation, immersed boundary methods, and even atomistic-scale modeling. At its essence, ppiclF's main purpose is to provide a unified and scalable interface for a user to solve the following system of differential equations d y --- = ydot, d t which are found in all of the previously given particle-in-cell applications.
