Best Thermal Analysis Software for Windows of 2025

Azore is software for computational fluid dynamics. It analyzes fluid flow and heat transfers. CFD allows engineers and scientists to analyze a wide range of fluid mechanics problems, thermal and chemical problems numerically using a computer. Azore can simulate a wide range of fluid dynamics situations, including air, liquids, gases, and particulate-laden flow. Azore is commonly used to model the flow of liquids through a piping or evaluate water velocity profiles around submerged items. Azore can also analyze the flow of gases or air, such as simulating ambient air velocity profiles as they pass around buildings, or investigating the flow, heat transfer, and mechanical equipment inside a room. Azore CFD is able to simulate virtually any incompressible fluid flow model. This includes problems involving conjugate heat transfer, species transport, and steady-state or transient fluid flows.

Thermal Desktop is a complete model creation tool. Objects such as finite element, lumped capacitance, and built-in finite differences can be combined in any way. Thermal-specific objects, such as insulation, heat loads and heaters, can be added to any model, from automotive components to manned satellites. Thermal Desktop allows full parameterization by using variables and arbitrarily complicated expressions instead of hardwired numbers. These variables, also known as symbols, enable models to be quickly manipulated by a few keystrokes. This makes it easy to update or maintain the model, perform sensitivity studies, and investigate what-if scenarios. This gives you access to SINDA/FLUINT’s optimization and reliability modules, as well as automatic model correlation.

Energy2D, a multiphysics simulation program based on computational physics and combining particle dynamics, models all three modes for heat transfer: conduction, convection and radiation. Energy2D runs fast on most computers, eliminating the need to switch between preprocessors and solvers and postprocessors that are usually required for computational fluid dynamics simulations. It allows you design "computational experiment" to test a hypothesis or solve a problem in engineering without resorting complex mathematics. There are also plans to support different fluid types and incorporate other types energy transformations. Energy2D's conduction is very accurate, but its convection and radioactivity parts are not. Energy2D should therefore be considered qualitative in cases involving convection and/or radiation. Energy2D has been used in more than 40 scientific publications.

RadCAD uses an ultra-fast Monte-Carlo ray-tracing algorithm that is accelerated by octa-trees to compute radiation exchange and view factors. C&R Technologies' innovations to the ray-tracing process resulted in a highly efficient thermal radiation software. RadCAD models diffuse or specular surfaces accurately, regardless of the density of nodes. The number of nodes is determined by the thermal solution, not by the accuracy requirements for the radiation. RadCAD uses user-defined databases for optical properties. Each surface coating defines absorptivity and transmissivity as well as reflectivity and specularity for both solar and infrared spectrum regimes. These properties can be defined in relation to incident angle, or even wavelength dependence.
