Femap Thermal Solvers

Femap’s thermal solvers add state-of-the-art thermal analysis solutions to the Femap environment and provide fast and accurate solutions to complex thermal engineering problems.

Using finite-element mesh, finite-volume based numerical techniques, the Femap Thermal Solver makes it easy to model nonlinear and transient heat transfer processes including conduction, radiation, and phase change. Accurate thermal analysis can be performed quickly and effectively, delivering the engineering insight and turnaround speed needed to ensure success within today’s rapid development cycles.

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.

Femap Advanced Thermal Solver

When your thermal analysis needs are more demanding, Femap Advanced Thermal Solver adds more advanced thermal modeling and simulation capabilities. These include 1D fluid network modeling, as well as free and forced convection. Femap Advanced Thermal Solver is ideal for sophisticated simulations such as radiation and spacecraft modeling, including both solar and orbital heating, orbit modeling and display, ray tracing, and articulating structures. In addition, the software includes more advanced features like custom user subroutines, model simplification, sub-structuring, and interfaces to industry-standard thermal codes.

Femap Flow Solver

The Femap Flow Solver adds state-of-the-art computational fluid dynamics (CFD) analysis solutions to the Femap environment and provides fast, efficient and accurate solutions to complex CFD problems.

Femap Flow software is a computational fluid dynamics (CFD) solution that is fully embedded into the native Femap environment. It provides fast, efficient and accurate functionality to simulate fluid flow and heat transfer for complex parts and assemblies. You also can explicitly couple Femap Flow with Femap Thermal and Femap Advanced Thermal for comprehensive thermo-fluid modeling of a wide range of multi-physics problems.

A sophisticated algebraic multi-grid solver provides the backbone to a complete CFD capability that is able to support the simulation of both laminar and turbulent fluid flow, low speed and high speed compressible flow, forced flow, natural convection and mixed flows, all with multiple inlets, outlets and internal flow boundary conditions. This memory efficient capability ensures that solutions are solved quickly and easily.


  • Allows investigation of multiple “what-if” scenarios involving complex assemblies
  • Provides extensive set of tools for creating CFD analysis-ready geometry
  • Allows troubleshooting of operational thermo-fluid problems prior to expensive physical prototyping time
  • Enables advanced CFD simulation within Femap such as high speed flows, rotational flows, non- Newtonian fluids, static motion of surfaces, particle tracking.
