 PeleLMeX is intended for students, researchers and engineers interested in understanding complex combustion processes
 by performing high fidelity simulations. Although it can be used to study laminar flames, its distinctive features make it
 particularly attractive for studying the fine scale flame/turbulence interactions in combustion applications where AMR is necessary
