An NEC designer describes his first Coolit project, a heat sink
for network servers, where he faced an extremely tight product
introduction schedule that did not allow for a lengthy learning
curve. The user downloaded the software, installed it and was up
and running within 30 minutes. He describes Coolit's online tutorial
that stepped him through the entire problem setup and analysis in
less than 2 hours, enabling him to built and analyze his first models
in a half day.
Coolit Technical Support recommended, that in order to speed up
analysis, he should break his problem into parts to assess the
sensitivity and relative importance of various design parameters.
Using this technique, together with Coolit's high speed native
Windows code, the user was able to calculate initial 150,000 cell models
in under an hour using a dual Pentium III 600 MHz PC with 512
Mbytes RAM, while the computer simultaneously
handled other engineering work. Final-stage calculations
averaged 500,000 cells. The user estimates that Coolit
thermal analysis sliced his development time to one-tenth
that required by previous mathematical approaches. The
match between analysis and testing proved to be so good that
the company has now almost eliminated prototypes.
