C&R
Technologies Announces Version 5.0 Product Releases
|
Littleton,
Colorado, November 14, 2006
C&R Technologies,
Inc. announced all new product releases for their tool suite; Version
5.0 installers are now available. This includes new releases
of SINDA/FLUINT, SinapsPlus®, Thermal Desktop®,
RadCAD® and FloCAD®."C&R
is very excited about the new features that have been introduced
in this 5.0 version," says Cindy Beer, international director
of Marketing and Sales. "We are excited about the major
expansions in SINDA/FLUINT supporting turbomachinery design and
analysis. This is a new industry we have been targeting over
the past couple of years which has required significant enhancements
to our product line. As always, we are being responsive to
our customers' and future customers' needs by adding features
that both make existing modeling tasks easier and open new areas
of modeling capabilities."
Customers under
current support contracts may download the updated versions for
free however they will need to contact
our support department for new license files. Customers who
no longer are under current support contracts must contact
our sales department to upgrade to the newer versions.
SINDA/FLUINT expansions
include but are not limited to:
- Turbomachinery
Expansions
- Turbine Device - A new connector device,
the TURBINE, is available for modeling turbines using either
performance maps or equations. Power, torque, and efficiency
calculations can be modeled, as well as sonic-limited flows.
User logic, the Solver, or co-solved ODEs can be used to
either balance torques or calculate dynamic shaft speeds
for turbopump systems, or for turbines and compressors
mounted on the same shaft.
- Compressor Devices - Two new connector
devices are available to simulate either variable (COMPRESS)
or positive displacement (COMPPD) compressors. Surging
and choking may be modeled, along with calculations of
power, torque, and mechanical efficiency.
- Thermodynamically Compressible Liquids
- In all prior versions, liquids were assumed to be thermodynamically
incompressible, although a tank wall compliance could be
used to simulate compressibility for waterhammer-type analyses.
Nonetheless, the lack of a fully compressible liquid option
resulted in regions of ambiguity (overlap of two equations
of state) for cold, high pressure fluids and created modeling
problems for systems employing cryogens, or for systems
such as Joule-Thomson expanders or transcritical carbon
dioxide heat pump and refrigeration cycles that traversed
this problem zone. A new COMPLIQ option has been added
to 6000 series FPROP blocks that eliminates such problems,
and compatible full-range fluids descriptions are now available.
- For rotating passages with walls that do not
co-rotate, new routines are available for calculating torque
in disks and cylinders for use with the path INTORQ=YES option.
- A new interpolation routine, D1D1DAH, permits
interpolations to use two arrays with hysteresis: one for increases
in the independent variable, and another for decreases.
- New PID controller options have been added
to permit advanced initializations (PIDINT) and to limit the
wind-up (PIDSETW).
- New map-style output routines are available
to provide detailed performance information and input echoing
for the new turbomachine devices: PUMPMAP, TURBMAP, COMPRMAP,
and COMPPDMAP.
- A complete
list of SINDA/FLUINT product updates is available on the world
wide web at www.crtech.com/sindaRelNotes.html.
Thermal
Desktop product expansions include but are not limited
to:
- AutoCAD
2007 compatibility
- New object
types are Torus, Ogive, Scarfed Cone, Scarfed Cylinder, and
Finite Difference Solid Cone Defaults have been added for Orbits
and Case Sets
- A new Logic
Manager has been added with objects for Array Interpolation,
Bivariate Interpolation, PID controllers, and User Fortran
Code.
FloCAD product
expansions include but are not limited to:
- New path types are: Capil, Turbine, Compress and, Comppd. These
are used to model turbines, compressors and positive displacement
compressors.
- IFace objects
have been added to model walls between fluid lumps.
- FTies objects
have been added to model heat transfer directly between two
lumps, with no mass exchange.
- Model checks
for coloring fluid objects based on input values has been added.
