Neper: Polycrystal Generation, Meshing and Post-Processing#
Neper is a free / open source software package for polycrystal studies. It generates 2D and 3D polycrystals, from simple tessellations to multiphase or multiscale microstructures, together with their crystal orientations, and meshes them into high-quality finite-element meshes. It also post-processes simulation results (especially from FEPX) and produces publication-quality images.
Tessellations from simple to multiphase or multiscale morphologies.
Meshes of tessellations, with uniform or per-grain mesh sizes.
Simulation directories from FEPX results, and their post-processing.
Images of tessellations, meshes and simulation results.
Note
See also Neper’s companion program, FEPX, a finite element software package for polycrystal plasticity. FEPX acts as a simulation tool for Neper.
Neper is developed by Romain Quey at CNRS and Mines Saint-Etienne.
