SINDA/G vs. 2.6 New Features Summary

The following is a list of major new features found on the 2.6 distribution CD. All of our
software has been upgraded to support the latest FlexLM license manager, and a few small
bugs were fixed. In addition, two new products are now on our distribution: SINDA/G for
ANSYS and the SINDARad radiation module.

SINDAG 2.6 and Thermal Studio
• Improved use of memory over version 2.5 allows larger models to be built.
• THR bang-bang source option – can now control when duty cycle integration starts
• CNV option for advanced contact coefficient
This computes the contact resistance at the interface between imperfectly contacting
materials. Three mechanisms contribute to heat transfer across the interface.
o Conduction – due to the direct contact between the materials
o Conduction – through the interstitial fluid
o Radiation
• SINDARAD support
• QRAD method (heat flux method used by SINDARad) integrated into TLIB & SGLITE
• Improved Thermal Studio
o Thermal Studio will read the SINDA/G keywords and routine names, such as
‘DRLXCA’ and ‘SNSOR’, from file ‘Thermal Studio.xml’ located in the SINDA/G
installation directory. By default, Thermal Studio will colorize these keywords and
routine names in its input file editor. User can add additional keywords in this XML
o Temperature conversion (TMPIN and TMPOUT) is added in the TSOUT routines.
o Storing multiple solution data in one SINDA/G run is supported.
o In Plot Data dialog, the ‘Node Sampling Rate’ combo box is added for node
selection. A ‘Solution’ combo box is added for choosing solution data if multiple
solution data is available.
o In Report dialog, the ‘Time Step Rate’ combo box is added for specifying a time
step sampling rate in report.
o The Plot Legend can be moved to any place within Plot Window.
o Result Name can be renamed.
o When called multiple times from a graphical modeler like Patran or FEMAP, the
previous setup of plots and reports is preserved allowing predefined plots from new
runs to be quickly viewed.

SINDA/G for Patran
o Interface to TSS
o Interface to SINDARAD, including multi-enclosure radiation, 2D enclosure radiation
and both the heat flux and radiation methods are supported .
o Improved efficiency for large radiation enclosure models

o Added Convert SGDB to txt file option under SINDA/G pull down menu. This feature
allows user to have a text file of the SINDA/G database.
o Added Run DB reader option under Analysis/Method. This feature allows the user to have
a text file of SINDA/G database. It is the same as above, but just accessed from a different
location within Patran.
o Modify the db reader to save memory, therefore to support bigger models.
o Enclosure load input form is modified for SINDARad edge radiation.
o User can now run a SINDA/G model and modify the model in Patran at the same time.
Before, Patran paused while the translator and SINDA/G were running.

o Interface to TSS
o Interface to SINDARAD, including multi-enclosure radiation, 2D enclosure radiation
and both the heat flux and radiation methods are supported.
o Improved accuracy for radiation enclosure models (full method)
o Improved efficiency for large radiation enclosure models

SINDA/G For FEMAP dashboard
o Individual setup panels for each radiation solver
o Once in the dashboard, multiple translations with radiation runs can be made
without going back to FEMAP betweens the runs.

SINDA/G for ANSYS (new product in distribution)
SINDA/G has been integrated transparently into the ANSYS Workbench modeling
environment to produce the SINDA/G for ANSYS* product. SINDA/G advanced thermal
models are directly created in ANSYS and the thermal results are post processed by ANSYS.
Interfaces to our new SINDARad module, TRASYS, NEVADA, TSS and THERMICA are
supported, allowing surface to surface radiation and orbital heating to be modeled in ANSYS
Workbench. Users familiar with building ANSYS thermal or structural models will be able to
use this product immediately.

SINDARad Radiation Module (new product in distribution)
SINDARad is a high speed view factor computational software program developed by
Network Analysis using technology acquired from Sandia National Labs. This technology
allows models to have tens of thousands of surfaces, and still solve quickly compared to
traditional radiation solvers. SINDARad is a module that integrates into Network Analysis FEA
to SINDA/G translators to compute the radiation conductors required by the SINDA/G
Thermal model. Models can be built in FEMAP, Patran or ANSYS Workbench using the
SINDA/G Plug-in. SINDARad incorporates a Windows based interface to make the product
user friendly with a short learning curve. SINDARad computes both the geometric view
factors (Fij’s), and the Radiation Exchange Factors (REF’s or Bij’s), allowing SINDARad to
produce traditional SINDA/G radiation conductors. A method to replace the potentially
large numbers of radiation conductors with heat fluxes into surfaces has also been
integrated into this product, allowing SINDA/G to run models with 100’s of millions of view
factors, yet not requiring additional memory for the SINDA/G model.

FEMAP 9.3.1
See the newfeat.pdf file in the FEMAP931 installation directory for details on these features.
One of the biggest features in 9.3.1 is the ability to use the model tree to edit individual loads
instead of using the cumbersome MODIFIY/EDIT/LOAD menu pick
