Best Free Thermal Analysis Software

SimScale is a cloud-based web application that plays a key part in simulation software for many kinds of industries. The platform allows the use of Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), and Thermal Simulation. It also offers 3D simulation, continuous modeling, and motion & dynamic modeling.

Based on computational physics, Energy2D is an interactive multiphysics simulation program that models all three modes of heat transfer, conduction, convection, and radiation, and their coupling with particle dynamics. Energy2D runs quickly on most computers and eliminates the switches among preprocessors, solvers, and postprocessors typically needed to perform computational fluid dynamics simulations. It allows you to design "computational experiments" to test a scientific hypothesis or solve an engineering problem without resorting to complex mathematics. Work is also underway to incorporate other types of energy transformations and support multiple types of fluids. The conduction part of Energy2D is highly accurate, but the convection and radiation parts are not 100% accurate. Hence, in cases that involve convection and radiation, Energy2D results should be considered qualitative. More than 40 scientific papers have used Energy2D as a research tool.
