NEiThermal Advanced

by Noran Engineering

NE/Nastran TMG (thermal analysis software) is a comprehensive modeling and simulation package. It provides fast and accurate solutions to complex thermal and fluid flow problems.

Description | More information | Demos | Pricing | Sectors | Platforms

The NEiThermal Advanced adds many advanced thermal and fluid flow modeling capabilities to the base package, such as duct flow modeling, including coupled convection and fluid flow analysis. An extensive set of modeling tools is provided for advanced radiation and spacecraft modeling, including solar and orbital heating, orbit modeling and display, specular reflections with ray tracing, and articulating structures. These tools are also complemented by a number of more advanced solver features such as custom user subroutines, model simplification, sub-structuring, and interfaces to industry thermal codes.

Solution Types

  • Transient
  • Steady-State
  • Linear
  • Nonlinear


  • Duct fluid flow network modeling with coupled forced and free convection simulation for multiple fluids and modeling both incompressible and compressible flows
  • Solar and orbital (spacecraft), diurnal and radiative heating including orbit modeling and interactive orbit display
  • Specular and hemicube radiation modeling with ray tracing and modeling of transmissive surfaces
  • Articulating structures for radiation modeling including translating and rotating joints and spinning spacecraft
  • Joule heating simulating electric resistance circuits
