Multiflash
is a sophisticated state-of the-art software product providing physical
and thermodynamic properties, with multiphase and multi-component
equilibrium calculations, for a wide range of substances. It is a
well-established product of Infochem
Computer Services Ltd. with many users worldwide, and not just in the
Oil and Chemicals industries. Multiflash
is used, for example, by a number of companies designing and developing
Fuel Cells. Multiflash
is available in a variety of forms, including Multiflash for Windows. To
find out more about Multiflash
and Infochem, follow the

Multiflash for MATLAB is a packaged solution comprising the standard Multiflash for
Windows product, plus the optional extra Multiflash Interface for Matlab
developed by khace.
We developed the Multiflash Interface for Matlab
to make the functionality of the
Multiflash for Windows Dynamic Link Library (DLL) accessible from MATLAB,
and to support the rigorous modeling of chemical processes and equipment
in Simulink
simulations.

Multiflash for Windows has optional interfaces for programming
in 'C', FORTRAN and Visual Basic. These interfaces comprise a set of
sub-program calls to the Multiflash for Windows Dynamic Link
Library (DLL). The Multiflash Interface for MATLAB
reproduces for the MATLAB
environment the complete functionality of the Visual Basic
interface as a simpler set of MATLAB
functions, with enhancements for vector, matrix and array
arguments. Version-6 of the interface extends the range of functions to
include MATLAB
equivalents of selected functions from the 'C', and FORTRAN programmer's
interface.

Multiflash is supplied with Infochem's
standard
INFODATA database of more than
121 fluid and 140 solid components. Other properties and components
may be available with license extension for optional additional databanks; which includes DIPPR
(AIChE) with 1450 fluid and solid components.
Available components are described on the Infochem
Web site page: Data
and Databanks, and in the Infochem
leaflet: Data and
Databanks, obtainable at this URL:

Properties calculated include: multiple-phase equilibrium data (concentrations, P&T), phase data, enthalpy, internal energy, entropy, compressibility,
thermal conductivity, surface tension, dew and bubble points, speed of
sound, molecular weight, Cp, and Cv.
Further information on the models and properties is available on the Infochem
Web site page:

Multiflash
is the solution of choice for several commercial simulation packages; see
for example: 'Infochem
Links' on the Infochem
web site. Multiflash for MATLAB has several advantages for Simulink
users:
- A wide range of physical properties is readily available.
- Property data is traceable to Infochem
or other industry-standard data sources, for Quality Assurance.
- Manual entry into simulation models of approximate physical properties through look-up
tables or off-line curve-fitting may be eliminated - removing the
risk of errors in model data entry.
- Modeling may be enhanced with reliable multi-phase/multi-component
flash calculations.
- Time-consuming iterative calculations may be offloaded from the Simulink
environment to the efficient solvers within Multiflash.
The Multiflash Interface for MATLAB provides interface
functions with familiar MATLAB
syntax. Calls to the interface functions may be incorporated in
simulations in several ways, including:
- From S-function models, to bring Multiflash
calculations into the simulation solution.
- From the Initialization code in block masks, to initialize block
parameters, prepare look-up tables, etc.
- From initialization scripts for the simulation, for automatic
initialization of workspace and block parameters, preparation of
look-up tables, etc.
Infochem have much
experience in interfacing Multiflash
to dynamic simulations. khace
has extensive experience in applying Simulink to the rigorous simulation
of processes and their controls. Both companies can offer Consulting
Engineering services to assist with developing and engineering a Simulink/Multiflash
based dynamic simulation.

MATLAB
has its interface capabilities for applications running within
the MATLAB
environment, which could include applications incorporating Multiflash
for MATLAB.
Because Multiflash for MATLAB includes the complete Multiflash
for Windows product, both the standard Windows and optional-extra
interface capabilities of Multiflash for Windows itself (e.g. the
Microsoft Excel interface) are readily available to the licensee of Multiflash
for MATLAB.

We maintain Multiflash for MATLAB, which includes The Multiflash Interface for
MATLAB, up to date with current releases of MATLAB.

Multiflash for Windows includes a DLL for 32-bit Windows
systems. Multiflash for MATLAB will therefore run under Windows
95/98 or Windows NT/2000/XP on personal computers with an Intel or equivalent
processor.
Multiflash for Windows is license protected by means of a hardware
device (dongle) and software protection key. A port driver is provided to run under
NT/2000/XP with the software protection key.
