Our CAD-embedded CFD simulation software enables engineers to conduct fluid flow simulation and heat transfer analysis in the CAD design environment. It has an intuitive interface, and critically, uses CAD geometry directly. This eliminates the time overhead of CAD data translation. It also allows engineers to conduct multiple design studies and evaluate results to see how modifications to geometry or operating boundary conditions influence performance. This makes simulation results available earlier in development for better decision making, and it supports more seamless communication with other CAD-driven engineering functions.
