FrackOptima NonPlanar3D is used to simulate the hydraulic fracture
  process that involves multiple stages and multiple fractures in
  unconventional reservoirs with parallel layer formations. Other
  features of NonPlanar3D simulator include:
  Heterogeneity of stress, toughness, pore pressure, leakoff, and spurtloss
  Heterogeneity of Young’s modulus, Poisson’s ratio will be available in the near future
  Linear elastic fracture
  Power law fluid flow
  Multistage slurry injections with multiple fluids and proppants
  Proppant concentration dependent slurry rheology
  Pressure dependent fluid leakoff
  Conserved proppant transport and settlement
  Crack tip mechanism covering viscosity and toughness controlled
  fracture growth as well as fluid lag
  Wellbore mechanics for fluid distributions along specified injection points
  Seamless screen-out simulation
  Shut-in simulation all the way to the final fully proppant-packed fracture
  Fracture intersection has not been completely implemented yet
  Simultaneous visualization and analysis of simulating results
