Introduction to Thermal Analysis Software

Many software companies have specific software for thermal analysis and related calculation; here we sort out numbers of most famous companies in this field. Examples which we show from their software is out of our activity but could refer you heat radiation analysis on various objects and places.

1- Hexagon/MSC Software

Gain a deep understanding of your product’s thermal behavior with some of the industry’s most capable thermal analysis solutions.

MSC’s thermal simulation solutions enable you to model thermal responses including all the modes of heat transfer, namely conduction, convection and radiation. Radiation view factors, critical for radiated energy flow calculations can be computed internally or imported from third party vendors providing options to our users. Additionally, both material properties and boundary conditions could be varied based on local temperatures, and can be modeled accurately and elegantly within MSC’s products.

The objective of a thermal study is often to understand the response and performance of a structure. Based on the modeling needs, chained or coupled analysis can be performed by engineers to study temperature variations and effects on structural behavior, both in terms of the stress response and failure. The multi-physics capabilities that involve thermal response can be extended further to include Joule heating and electromagnetic effects for a better representation of physical behavior.

MSC Software is used for many types of thermal simulations:

  • Ablation conductors
  • Advanced convection
  • Temperature dependent properties
  • Contact mounting resistance
  • Heating due to friction
  • Environment effects on optical systems
  • Orbital heating
  • Phase change modeling
  • Radiation view factors
  • Steady state and transient heat transfer
  • Thermal structural coupling
  • Electro-upsetting simulation

2- SimScale

Perform thermal simulations in your browser using SimScale’s cloud-based heat simulation software.

Many materials and products have temperature-dependent characteristics; this makes analyzing the impact of heat and ensuring thermal management of structures and fluids crucial in product development. The SimScale cloud-based simulation software platform allows you to predict the airflow, temperature distribution, and heat transfer. Use SimScale’s thermal simulation as a heat transfer simulator to analyze and optimize your product early in the design phase.

Thermal – Structural Analysis

SimScale’s thermal simulation software component enables you to perform both thermomechanical and heat transfer analyses. The thermal analysis software takes into account the energy balance of the system. When investigating thermomechanical components, the effects of thermal loads on solids can also be included. For many industrial applications, simulating the stress response to thermal loads and understanding failure is essential. Applications include polymeric materials, valves, pipes, basket strainers, PCB, pressure vessels and more.

Heat Transfer Simulator

SimScales’s heat transfer simulation allows you to simulate coupled heat transfer in fluids through convection and heat transfer in solids via conduction. The thermal analysis software parameters are determined by the type of fluid convection such as natural, mixed or forced convection. Some of the areas in which it can be used are heat sink design, electronics cooling, heat exchangers, automotive thermal management, nuclear reactors, and beer brewing.

Simulation Software Enabled Conduction

Conduction refers to a heat transfer between substances that are in direct contact with each other. In theory, heat energy passes from the hot to the cold end of the substance and is directly related to the conductivity of the material. The SimScale thermal simulation software offers a module for various types of applications where heat and energy are significant study parameters.

3- Siemens

Thermal Simulation

Ensure thermal performance

Thermal management is a major consideration for a wide range of products, including industrial machinery, automobiles and consumer electronics. The objective of any thermal management solution is to maintain a product’s temperature within a range that is optimal for performance. Accomplishing this may require the removal or addition of heat, either passively or in an actively managed fashion, and this can be evaluated using thermal simulation software.

Simcenter includes comprehensive, best-in-class thermal simulation capabilities that can help you to understand the thermal characteristics of your product and subsequently tailor your thermal management solution for optimal performance.

Thermal simulation includes a number of capabilities to cover different applications.


Startup uses Simcenter Engineering Services and Simcenter STAR-CCM+ to develop heat pump that reduces energy costs.

Siemens Digital Industries Software services and solution enable ThermoLift to integrate automated design optimization, allowing simulation to drive the design process.

4- AARK Engineering GMBH/THESEUS FE Software

Simulate Radiative Heat Transfer

Solar radiation simulation results on airplane

THESEUS-FE comprises many different mathematical models for representing energy exchange by thermal radiation. The overall spectrum of thermal radiation is separated into two bands, the so-called short-wave and long-wave radiation ranges.

Short-Wave Radiation

The short-wave range includes all wavelengths below the ultraviolet spectrum, the entire spectrum of visible light and higher-frequency parts of the infrared spectrum. This is the typical domain of energy sources dominated by radiative energy exchange, including solar energy, domestic light sources and infrared radiators. This kind of radiation exchange usually takes place in a highly directional manner. Within the radiation solver, material parameters and interaction effects such as specular and diffuse reflection, transmission and absorption can be treated in a physically correct manner as a function of wavelength. Major effects covered by the short-wave radiation solver include:

  • diffuse and specular reflection
  • opaque and transmitting materials
  • transmittance depending on the angle of incidence
  • refraction in transparent materials, e.g. to model optical lenses in automotive headlights
  • wave-length dependent material properties for absorption, transmission and reflection
  • various specialized sources of radiative energy, e.g. to model the sun, point-sources or generally radiating surfaces

Long-wave radiation

The long-wave range is used to model intra-model thermal radiation energy exchange based on the current part temperature. Depending on the temperature, this type of thermal radiation can reach into the visible spectrum but is usually maximal in the non-visible, deep infrared range. The intra-model radiative exchange is modelled in a highly efficient manner using view factors calculated between all the surfaces of the finite element mesh.
