NX TMG Advanced Flow for Advanced Simulation environment is an add-on module to NX TMG Flow. It leverages the computational fluid dynamics (CFD) solver to simulate complex fluid flow phenomena both accurately and efficiently.

NX TMG Advanced Flow solves practical engineering challenges such as:

• High speed compressible flow to find choking conditions or the location of shock waves.
• High speed flow in rotating equipment.
• The proper physics within multiple parts rotating with respect to each other.
• Aerodynamic heating and ablation (may require coupling with NX TMG Advanced Thermal).
• The impact of large scale environmental contaminant dissemination for a given disaster scenario.
• Complex turbulent phenomena.
• Multi-species fluid mixing.
• Rotation and translation motion influencing the fluid flow.

• Buoyancy line of offshore and marine vehicules.
• Size and power requirements in the case of a slurry pump application.
• Head losses and volume flow rates within a blood pump system.
• Drag and lift forces with out most accuracy.
• Humidity effects such as condensation on windshields.

• Aerodynamic shape.
• Turbomachinery components.
• Air intake assembly.
• Composite material oven components, including evaporation.
