Steam Tables |
Capability: PocketSteam makes it possible
to carry a complete set of steam tables on any of the battery-powered handheld
computers that run the Microsoft Windows CE 2.0 operating system. PocketSteam
provides both thermodynamic and transport properties, including Prandtl number
and critical velocity. It also includes a built-in turbine expansion calculation.
The calculator can use a wide range of English and metric units for each
property. The user selects the display format and display accuracy for each
property.
The user can name any number of points and store all of their properties
for later use. The stored points can be copied to the Windows clipboard and
shared with other applications, such as Microsoft's Pocket Excel. They also
can be stored in files that can be moved to a desktop computer and used by
the companion desktop program. On-line help describes all features of the
program.
Hardware: Handheld pocket computers running the Windows CE 2.0 operating
system on MIPS and SH3 processors.

| Pressure
Vessels |
Capability: COADE Inc. has released
new versions of its PVElite integrated vessel design and stress analysis
program and its CodeCalc software for the design and analysis of pressure
vessel and heat exchanger components. PVElite version 3.40 includes ASME
Section VIII, Division 1, 1998 edition, an expanded database of yield stress
versus temperature, support for ASME Code Case 2290, and BS-5500 (British
Standard) code additions for isolated nozzle, conical, and combined stress
calculations. In addition to the ASME Boiler and Pressure Vessel and the
BS 5500 codes, PVElite includes pressure-vessel standards such as ASCE No.
7, Uniform Building Code, National Building Code, ANSI B16.5, TEMA, and WRC
Bulletin 107. The software can be used to design tall towers, horizontal
vessels, pots and pans, and individual vessel components.
CodeCalc version 6.10 incorporates the same ASME standards as does PVElite.
The database of yield stress versus temperature has been expanded, and unit
options have been enhanced. In addition to calculating pressure and wall
thickness, CodeCalc evaluates loads from supports and attachments.
Hardware: PVElite and CodeCalc require an IBM-compatible PC with Windows
95, 98, or NT.

| Free-Form
Surfaces |
Capability: FastSurf 98, a free-form
surface modeling program for CADKEY 98 or CADKEY Wireframe, generates swept
and lofted surfaces, surfaces of revolution, offset surfaces, fillet blends,
variable radius fillets, and tabulated cylinders. Users can trim surfaces
with splines, curves, and other surfaces. FastSurf 98 also performs surface
intersections and entity projection. The program includes a module for creating
and analyzing surface vectors and planes, as well as surface and spline editing
tools to alter the shape of a surface.
FastSurf 98's surfaces can be converted to ACIS surfaces that can be used
interactively with other ACIS solids, surfaces, and sheet bodies in CADKEY
98. The user can stitch ACIS solids and surfaces into one body, and trim
or subtract ACIS bodies to construct a 3-D hybrid model, a capability that
is useful in building complex, organic shapes.
