Data-Sheet     • Technical Brief

Why have people switched?

Cadence’s research has found that many thermal engineers are unhappy with traditional simulation packages. One reason is the slow speed at which many packages solve their simulations.

30% of thermal engineers must spend over a day building their simulation models

41% say that they will typically spend over an hour gridding their designs

66% of thermal engineers spend a day or more solving their simulations

Celsius EC is Fast

An independent side-by-side comparison conducted by Rohde & Schwarz found it was faster at preparing the model, pre-processing & solving than a comparable thermal simulation SW.  

Rohde and Schwarz Benchmark

Rohde and Schwarz created 12 thermal models of their equipment in Celsius & a competitor’s SW.

The competitor’s software failed to solve 7 of the 12 models. The remaining 5 were solved with “low detail”

Celsius solved all 12 models in “high detail”

The Celsius Thermal Solver utilizes innovative multi-physics technology to address challenges. By combining finite element analysis (FEA) for solid structures with computational fluid dynamics (CFD) for fluids, Celsius enables complete system analysis in a single tool!
