FEMAP ADVANCED THERMAL SOLVER

The Femap Advanced Thermal Solver adds a number of more advanced thermal modeling and simulation capabilities to the Femap Thermal Solver package including 1D fluid network modeling and free and forced convection. An extensive suite of thermal modeling tools are provided to allow users to define more advanced and sophisticated thermal simulations, such as radiation and spacecraft modeling, including solar and orbital heating, orbit modeling and display, ray tracing capabilities, and articulating structures. These extensive modeling 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.

Finite volume FE-based thermal solver technology to efficiently simulate complex heat transfer phenomena The Femap Thermal solver features high order finite volume FE-based technology to accurately and efficiently simulate heat transfer phenomena. It combines the versatility of FE-based analysis with the accuracy and efficiency of a finite-difference scheme. Femap Thermal solver technology facilitates simulation of Femap parts and assemblies within complex thermal siemens plm  femap environments. Its solver and modeling features include :

Solver capabilities

  • Steady-state (linear and nonlinear)
  • Transient (linear and nonlinear)
  • Material nonlinear thermal properties
  • Axis-symmetric modeling
  • Cyclic thermal simulation
  • High speed rotational effects
  • Iterative conjugate gradient solver technology
  • Fully coupled conduction, radiation and convection heat transfer simulation
  • Electrical joule heating
  • Ray-tracing including ray extinction and heat dissipation within participating media
  • Latent heat of material phase changes and thermal ablation modeling
  • 1D hydraulic networks for explicit thermo-fluid couplings

Benefits

  • Allows for investigation of multiple “what-if” scenarios involving complex assemblies
  • Facilitates building of assemblies by modeling heat flow between unconnected parts and components
  • Enables the user to simulate strong and fully-coupled thermo-fluid interactions, including proper treatment of radiative heat transfer
  • Supports mapping results to a Nastran FE model for thermo-elastic analysis
