Our review
Pros
  • Includes solvers for fluid flow, turbulence and multiphase simulation
  • Provides native mesh tools and parallel workflows using domain decomposition and MPI
  • Supports ParaView-based visualization and exports including VTK and EnSight
  • Offers topology, shape, sizing, and bead optimization methods
  • Supports manufacturing conditions, including casting restrictions
  • Integrates optimization workflows with Abaqus/CAE and SIMULIA
Cons
  • Focused on fluid simulation rather than broad multiphysics coverage
  • Simulation cases are configured through text-based dictionaries
  • Community and documentation are the listed support channels
  • It is an optimization companion, not a broad standalone CAE suite
  • Pricing is handled through sales rather than published plans
  • Cloud simulation access is tied to SIMULIA workflows
