NX TMG Advanced Thermal for Advanced Simulation environment is an add-on module to NX TMG Thermal. It leverages the TMG-Thermal heat transfer solver to accurately and efficiently simulate complex thermal phenomenon.

NX TMG Advanced Thermal solves practical engineering challenges such as:

• Aero-heating (may require NX TMG Advanced Flow).
• Phase change and thermal ablation.
• Thermal behaviour in high speed rotating equipment.
• Joule heating under various electrical loads.
• Laser and optical systems with ray-tracing.
• Thermal refraction in optical and other participating media.
• Infrared (IR) signature of large system in various environmental settings.
• Diurnal environmental solar heating (including cloud, altitud, longitude and latitude effects, object orientation, pollution effects and other attenuation effects).
• Implicit correlation-based free and forced convection heat transfer.
• Hydraulic network heat transfer.
• Specular, transmissive surfaces and other advanced radiation heat transfer applications.

• Permits simulation of advanced optical properties:
• Direction-dependent emissivity.
• Bidirectional reflectance distribution functions (BRDF).
• Fully compatible with other TMG radiation analysis methods.
