What is Celsius Thermal Solver?

Celsius Thermal Solver is an electrothermal simulation tool that allows for testing models under thermal, stress, and electric scenarios. Celsius enables the simulation of entire systems to show the user how a system dissipates power and heat; it can highlight any hotspots to the designer, which can then be improved.

Simulating a complete system from the perspective of a system design, such as a cellphone or laptop designer, can be highly beneficial. As mentioned earlier, this can lead to finding thermal flaws early in the design process. When these thermal hotspots are found early on, they can be removed or redone to minimize the heat concentration, mitigating the risk of significant redesigns later in the design process.

Celsius Thermal Solver enables designers to set up and run steady-state or transient simulations. The former provides a single 2D temperature map for layers and components. In contrast, the latter provides maps for each simulated time instant and warmup curves at the cost of longer simulation time.

Celsius uses an innovative massive parallel solver technology. This technology allows for reduced memory usage and 10x faster simulation speeds than legacy solutions. It includes a powerful finite element analysis (FEA) field solver to analyze both transient and steady-state and heat conduction in complicated solid structures and utilizes a computational fluid dynamics (CFD) engine for the convection and radiation heat transfer analysis.
