It lets designers relatively quickly evaluate concepts and
correct thermal problems long before the proto type phase. Our
company provides enclosures, backplanes, and subracks, as well
as accessories such as power supplies, front panels, end
monitors, and extender boards. We use Flotherm to calculate air
velocities and flow rates over slots and cards and for detailed
heat-transfer analysis of embedded-chassis designs.  When
developing a chassis to be used with high-capacity, high-power-
dissipating 6U VME or Compact PCI-based electronics, the first
step was to model the enclosure and circuit card. Flotherm's
extensive materials library came in handy while modeling the
enclosure because it contains a wide range of common alloys.  We
primarily design around plug-in cards specified by customers. So
we frequently exploit the software's capability to generate
compact models or library assemblies. After a detailed analysis
of the card in question, I used volume-resistance elements,
computationally efficient represen
