WILSONVILLE, Ore., Nov. 12, 2015 /PRNewswire/ -- Mentor
Graphics Corporation (NASDAQ: MENT) today announced the newest
version of its market-leading FloTHERM® product, the industry's
most powerful and accurate computational fluid dynamics (CFD)
software solution. The FloTHERM product was developed to quickly
identify potential thermal issues early in the design process to
avoid expensive late stage re-design and warranty costs arising
from thermal failures in the field. The newest version of the
FloTHERM product delivers an automated method to calibrate
simulation models to match transient thermal measurements recorded
with the Mentor Graphics® T3Ster® hardware. As a result, the
FloTHERM product can help maximize simulation data accuracy and
provide additional insight into product reliability – a necessity
for the automotive, aerospace and electronics products
industries.
Mentor Graphics T3Ster product is an advanced thermal tester for
thermal characterization of IC packages, LEDs and systems which
produces extensive thermal characteristics rapidly. The
industry-leading T3Ster test system delivers highly accurate,
real-time measurements of heating and cooling transients based on
its advanced implementation of the JEDEC static test method
(JESD51-1) and can now be considered to be 10X better than
alternative solutions.
The new FloTHERM product can convert a simulated transient
thermal response into a structure function curve using the same
mathematical process utilized by the T3Ster product. These
structure function curves are known to correlate with the physical
structure of the device, and are thus the ideal platform to compare
simulation with test data. Differences between the structure
functions indicate that some aspect of the simulation model is
incorrect; typically dimensions or physical properties that are
difficult to measure directly such as thermal interface material
(TIM) thicknesses or interfacial thermal contact
resistances. The new FloTHERM version uses optimization
methods to change the model inputs and drive the simulation
structure function towards the experimental structure function
until a match is achieved. This match indicates that the
FloTHERM model is fully calibrated and will respond correctly and
accurately in any transient application. Package manufacturers
can now certify supply chain models, by providing evidence about
the thermal performance of the component in customer applications
along with the model itself.
"Working with a fully-calibrated model of a package is often
critically important in steady state and transient analyses when
accurate prediction of the junction temperature is the objective,"
said Ir. Clemens Lasance, principal
scientist at Philips Research (retired) and consultant at
SomelikeitCool. "The calibration is usually performed by creating a
structure function to be compared with the one measured with a
T3Ster in the lab. The latest version of FloTHERM embeds an
automated ability to fine-tune a FloTHERM model to achieve this
match, making this best practice modeling methodology far more
accessible to thermal engineers."
Additional features in the new FloTHERM product include:
- Joule heating – DC electrical calculations are now supported
for joule heating effects to be accurately predicted, enabling
power distribution net analysis and bus bar design to be
performed.
- FloMCAD Bridge enhancement – 64-bit support enables larger MCAD
designs to be imported into the FloTHERM product. In addition, the
voxelization method used to translate MCAD geometry into analysis
objects was re-engineered to be 20 times faster and much smarter,
ensuring that coincident faces on different bodies maintain that
connection after translation.
- Localized grid spaces – overlapping localized spaces can now be
created. The FloTHERM product makes it easy to construct an
efficient grid for large cluttered geometry because the arrangement
of localized grid spaces is no longer a concern.
- DCIM Software Development Kit – The kit includes everything a
DCIM supplier needs to drive FloTHERM, capture the simulation
results, and display them within their DCIM software suite. "Mentor
Graphics' DCIM Software Development Kit provides all the hooks DCIM
firms like us need to integrate FloTHERM with software such as
FieldView 2015™ with ease. This enables us to drive FloTHERM from
within our software suite and display the results, including the
way shown in the Excel-based example," added Dr. Fredrick Dirla, Jr, CEO of Fieldview Solutions.
"I applaud Mentor for democratizing CFD for data center simulation
and eliminating guess-work."
"By using an uncalibrated model for simulation,
manufacturers run the risk of simply guessing performance.
Calibrating the package model constants ensures the product will
respond accurately in all steady state and transient applications,"
stated Roland Feldhinkel, general manager of Mentor Graphics
Mechanical Analysis Division. "We continue to invest in leading
simulation and measurement technologies to provide our customers
with superior and productive capabilities to handle their most
complex thermal management challenges."
