PC3D is a PC based general purpose thermal computer modeling program. Most
any heat transfer problem can be simulated using PC3D allowing you to find
the hot spots, thermally optimize a design and have confidence that the
design will meet your thermal requirements before you build it.

PC3D has an integrated, graphical and interactive environment. Drop down
and pop up menus and dialog boxes make generating models easy and
efficient. Colors provide quick feedback of element types, properties and
temperature results. PC3D has a fast built-in steady state and transient
finite difference solver. Models represented by literally tens of
thousands of resistors can be solved on the PC. The accuracy has been
proven against classical solutions and comparisons with other tools such
as NASTRAN, ANSYS and SINDA.

PC3D requires a 386, 486 or Pentium processor with at least 4Mb of RAM. A
mouse and VGA monitor is also required.

SINDA model generation

Any PC3D model can be converted into a complete ready-to-run SINDA model.
Both SINDA/G and SINDA '85 versions are supported. PC3D generated FORTRAN
code in the variables block so a PC3D results file is generated providing
post processing capabilities as well. Because PC3D and SINDA are so
compatible, Network Analysis Associates Inc. sells a version of PC3D as
their pre and post processor to their SINDA/G customers.

Transient plotting

Nodal temperature of the model can be plotted using the built-in
temperature versus time plotter.

PC3D supports printing to nearly 850 printers. Any image on the screen can
be printed. All aspects of the printing can be taylored. You can print in
color or in 8 or 16 gray shades, landscape or portrait. You can print
directly to the printer or to a file.

Easy "what if" runs

All elements, boundary conditions and heat loads can reference the property
table. Changing a number in a cell can change a bracket material from
copper to aluminum, a constant heat load to one which varies with
temperature. Running those 10 cases needed to optimize the design is now
simple. Being easy to perform "what if" cases promotes a better thermal
design and also helps you better understand the problem.

NASTRAN Interface

NASTRAN is a popular thermal and structural finite element modeling program
from MacNeal Schwindler Corp. PC3D comes with a conversion utility which
will convert PC3D models into NASTRAN models and NASTRAN models into PC3D
models.

Cost

PC3D Comes in two versions, Full and Limited. The limited version limits
model size to 2000 nodes. The cost of the full version is only $995. and
the limited is only $695. Harvard Thermal offers a significant university
discount, the full version for only $100. PC3D comes with a 30 day money
back guarantee and one year of maintanance. The 200 page manual fully
describes how to use the program and contains example models and a
tutorial.

Free Demonstration Package

The free demonstration software will show you how to load, view and create
models. A model of an air cooled heat sink is created from start to
solving and post processing automatically. You can also use the
demonstration version of PC3D manually and see how easy it is to create
complex thermal models.
