 Make the Engineers, Accountants, and
Your Boss Happy by Choosing SC/Tetra Software for Your CFD
Simulations
When making any business purchase, your
objective is to achieve value: Engineers want power, capability,
functionality, and ease of use. Accountants want the lowest
price. Your boss wants results. If you’re considering purchasing CFD software, here are just a few reasons why you should be
giving SC/Tetra CFD software serious consideration.
SC/Tetra is full function CFD
software with Features and Capabilities that Exceed Even the
Most Well Recognized CFD software on the Market
SC/Tetra is true, full function, general purpose CFD software
that’s flexible enough to grow with your simulation/modeling
needs. It can be used for an unlimited number of flow
applications including compressible/incompressible, transient,
reacting, mixing, rotating machinery, conjugate heat transfer
(including radiation), and even free surface flows. With these
capabilities SC/Tetra is powerful enough to be the primary,
general purpose CFD software used by several major Asian
automotive manufacturers, yet it is PC based so it brings all
these same capabilities to single users.
Just how good is SC/Tetra? The Japanese Society of Automotive
Engineers (JSAE) rated CFD software in a paper entitled “CFD
Commercial Codes and Computers Comparison”
Proceedings# 20014696 (2001).
In addition, SC/Tetra was designed from its inception to be
PC/Windows based. This makes it faster and more memory efficient
than most of today’s so-called PC based CFD software most of
which were initially designed for UNIX platforms.
Finally an End to Modeling
Nightmares
You don’t have to be the CAE business very long to know that
building good models is
probably the most formidable obstacle standing between you and
success. Those demonstrations of going from CAD geometry to
volume mesh with one mouse click may work for simple geometries.
But they rarely work for the more complex, real world
situations. Cracks, overlapping surfaces in the volume mesh,
skewed cells, or insufficient grid density, any of these and
countless other mesh related problems can keep you from getting
a converged solution. And frequently it can take what seems like
forever to find the problem since you may have to sift through
thousands of cells. If you’re fortunate you may have access to
specialized 3rd party software to help diagnose your mesh.
That’ll cost you some money. You might also wonder why CFD
software doesn’t come with built in mesh diagnostics and mesh
repair capabilities since these problems are so prevalent with
CFD volume meshes.
Eyesight Going Bad Looking for
All Those Microscopic Mesh Defects?
The SC/Tetra CFD software preprocesor contains built in
diagnostics for identifying problematic cracks, leaks, and
intersecting surfaces in the volum mesh.
It also contains mesh repair functions so you can fix these
problems right within SC/Tetra itself. You won’t need to buy any additional software.
In addition, SC/Tetra calculates mesh skewness parameters so you
 can continuously track the quality of your mesh. When you’re
trying to adjust the grid density, say for example in regions of
high gradients, some software packages require you to adjust the
grid density on the surface mesh in order to change the volume
mesh. This provides very little control of the volume mesh
density and usually puts more cells where you don’t want them
and takes them out where you want them. SC/Tetra’s Oct-tree
meshing process gives you unparalleled control of the volume
mesh. You can easily increase or decrease the mesh density
exactly where you want to. Talk about control.
Full Functionality and 30 – 50%
Less Expensive
In the world of CFD you’ll find the cost of a license can vary
anywhere from FREE to upward of $25 -30,000 per year. Freeware
is usually very limited and not recommended. In contrast the
high end software is multi-purpose software and very widely used
throughout the industry. In fact, the companies developing and
selling these general purpose CFD codes hold upward of 80-85% of
the CFD market share. If you’re a large company purchasing
several software licenses, the larger CFD software companies
will offer you a packaged, discounted price. However, if you
only need a few licenses, you’ll probably have to pay full price
for each license.
SC/Tetra’s value proposition is much more promising. SC/Tetra is
full general purpose CFD software with unparalleled
preprocessing capabilities. Its capabilities rival or exceed the
most popular CFD software packages on the market today. It accepts standard geometry data formats so
it’s compatible with most of the standard CAD software used in
industry. How much does an SC/Tetra annual license cost? Try
30-50% less than its competitors. In today’s cost conscious
business world, that should be enough to raise some interest.
