Documentation
The documentation
and examples on this page are provided to help novice MODEL.LA users get
started and to help intermediate users learn more about what they can
do in MODEL.LA. If you would like to make a contribution (e.g., an interesting
MODEL.LA model or case study that you have developed), please contact
us so we can make it available here.
All MODEL.LA documentation
is provided in the form of PDF files. These may be viewed and printed
using the free Adobe
Acrobat Reader.
The following
documentation is available:
In addition, the research concepts
behind MODEL.LA are described in Jerry
Bieszczad's Ph.D. thesis.
- Introductory
Tutorial (latest
version 0.1):
We recommend that beginning
all MODEL.LA users get started by reading and completing the MODEL.LA
Introductory Tutorial. It provides step-by-step instructions for
the modeling and simulation of a jacketed CSTR in MODEL.LA. More importantly,
it illustrates use of the primary interface elements that the user
interacts with during a MODEL.LA work session.
An enhanced HTML
version of this tutorial has also been contributed.
- Example
Models:
After completing the tutorial,
beginning users can look through the example models provided in the
MODEL.LA installation. These may be found in the Examples
subdirectory off the main MODEL.LA installation directory (e.g., C:\Modella\Examples\).
These examples and any other MODEL.LA model files are opened from the
File/Open... option
in the main MODEL.LA menu bar.
Summaries
of installed example models are available.
If you have developed an
interesting model or case study in MODEL.LA that you would like to share
with the MODEL.LA community, please let us know
and we can make it available here.
- Acetic
Anhydride Process Design Case Study
(latest version
0.1):
A case study describing the
hierarchical
design of a process for acetic anhydride manufacture is available.
This case study begins by considering the entire process as an input-output
structure. Each subsequent level of the design adds additional detail
until the process is modeled down to the level of individual trays in
a distillation column.
This case study assumes minimal
familiarity with MODEL.LA, but users who complete the entire case study
are well on their way to becoming MODEL.LA power users.
The MODEL.LA model and simulation
files for this case study are provided in the examples subdirectory
of the MODEL.LA installation (e.g., C:\Modella\Examples\11_acetic_anhydride\).
- User's
Guide (latest
version 0.1):
A draft of the MODEL.LA
User's Guide is available.
The user's guide provides instructions on how to complete common modeling
tasks in MODEL.LA.
Many elements of the
MODEL.LA graphical user interface have been redesigned and many others
added since the user's guide was first written. An updated user's
guide may be downloaded from this page when it becomes available.
- Reference
Manual (latest
version 0.1):
A draft of the MODEL.LA
Reference Manual is available. The reference manual provides details
about the function of every dialog window, menu option, and button in
MODEL.LA.
Many elements of the MODEL.LA
graphical user interface have been redesigned and many others added
since the reference manual was first written. An updated reference manual
may be downloaded from this page when it becomes available.
Summary
of Example Models:
Examples provided with the
latest installation of MODEL.LA are listed below. The corresponding model
files may be found in the Examples
subdirectory off the main MODEL.LA installation directory (e.g., C:\Modella\Examples\).

model or case study in MODEL.LA that you would like to share with the
MODEL.LA community, please let us know and

This HTML
version of the MODEL.LA tutorial provides step-by-step instructions
for the modeling and simulation of a jacketed CSTR in MODEL.LA. It also
features hyperlinks to supplementary information about MODEL.LA that
is not contained in the PDF version of the tutorial.
The use of hyperlinks in
this tutorial allow a user to contextually learn more about the impact
of their modeling assumptions on a model. In a similar manner, they
also provide access to additional details about the features and capabilities
of MODEL.LA.
