Mentor Graphics Corporation (Wilsonville, OR) offers the next generation of its FloTHERM® 3D computational fluid dynamics (CFD) software for electronics cooling applications. FloTHERM allows engineers to implement virtual prototypes to simulate airflow, temperature, and heat transfer in electronic systems. The patent-pending technology in the FloTHERM v.9 software provides Bottleneck (Bn) and Shortcut (Sc) fields so that engineers can identify where heat flow congestion occurs in the electronic design and why. It also identifies thermal shortcuts to quickly and efficiently resolve the design problem. The Bn and the Sc fields elevate the use of simulation from an observation tool that identifies heat management problems, to an effective thermal design problem-solving tool that suggests potential solutions to the designer.
