Stitch – IO Library for highly localized simulations
Project • IO libraries typically focus on writing the entire simulation domain for each output. For many computation classes, this is the correct choice. However, there are some cases where this approach is wasteful in time and space. The Stitch library was developed initially for use with the SPPARKS kinetic monte carlo...
