Flow Simulation

As part of the Simcenter 3D simulation package, the Flow Simulation module is a fully-integrated add-on module to Simcenter 3D, offering users the ability to simulate fluid flow for assemblies and complex parts. The Flow Simulation module’s fast and accurate simulation capabilities add valuable information and comprehension to the design and development phases of a product’s lifecycle, helping reduce costs of material and production. Applications for the Flow Simulation module’s CFD capabilities stretch across various industries including automotive, aerospace and defense, medical, consumer products, power generation, electronics and semiconductors, and more.



Benefits of using the Flow Simulation module include:

  1. Leverage virtual prototyping to cut costs from physical protoypes
  2. Quickly go from design to simulation environment with platform consistency to obtain quicker CFD results
  3. Reduce modeling time for all design-analysis iterations
  4. Combine with Simcenter 3D Thermal Analysis module to perform thermo-fluid multiphysics analysis for even more insight



Solution types include:

  • Steady-state and transient analysis (adaptive correction multigrid solver)
  • Laminar flow usable locally within porous blockages
  • Turbulent (k-ε, mixing length), laminar and mixed flows
  • CFD solution intermediate results recovery and restart
  • Heat loads and temperature restraints on the fluid
  • Forced, natural and mixed convection
  • Fluid buoyancy
  • Multiple enclosures
  • Multiple fluids
  • Internal or external flows
  • Losses in fluid flow due to screens, filters and other fluid obstructions (including orthotropic porous blockages)

The Simcenter 3D Flow Simulation module’s integration into the NX portfolio allows users to benefit from the Simcenter 3D environment. As the CFD model is synchronized with the NX design and assembly intent through NX data associativity, designers, engineers, and fluid specialists can avoid any transfer of additional input files or geometric manipulations or conversions that would break the associative link between NX geometry and simulation tasks. This means that the mesh is automatically updated with every design or assembly modification.
