= EMSO =

EMSO is the acronym for Environment for Modeling, Simulation, and Optimization.
[[Tr(begin)]]EMSO é a sigla para ''Environment for Modeling, Simulation, and Optimization''.[[Tr(end)]]

EMSO is a graphical environment where the user can model complex processes simply selecting and connecting
the equipment models.
[[Tr(begin)]]O EMSO é um ambiente gráfico onde o usuário pode modelar processos complexos simplesmente selecionando
e conectando os modelos dos equipamentos.[[Tr(end)]]

== Features ==

The main features of EMSO follows:
[[Tr(begin)]]Principais características do EMSO:[[Tr(end)]]

 * Entirely written in C++
 * A fairly portable code, currently available for '''Windows''' and '''Linux''' but can be compiled for other platforms if desired
 * It is an Equation-Oriented simulator
 * The unique Equation-Oriented simulator with '''units-of-measurement checking''' for the equations
 * A large set of [wiki:Functions built-in functions]
 * Models are written in a '''modeling language''', the user does not need to be a programmer
 * Models are converted to system of equations '''in memory''', no compilation or linking is needed
 * An '''open''' library of models, called [wiki:EML]
 * Built-in code for symbolic differentiation which enables the system to solve '''high-index''' problems
 * Built-in code for automatic differentiation which makes the system '''very efficient'''
 * Can make use of '''machine optimize BLAS''' routines
 * Currently support:
   * static simulation
   * dynamic simulation
   * static optimization
   * parameter estimation of static models
   * parameter estimation of dynamic models
 * A graphical user interface which can be used to model development, simulation execution, and results visualizing
 * A system of '''PlugIns''' where the user can embed code written in C, C++ or FORTRAN into the models
 * A very modular system - all solvers are DLL's and the user can even write their own NewSolver

== Models ==

In most cases the models available on the library of models [wiki:EML] can be used without modification.
But the user can develop its own new models using the EMSO modeling language.
[[Tr(begin)]]Na maioria dos casos, os modelos disponíveis na biblioteca de modelos [wiki:EML] podem ser utilizados sem modificações.
Mas o usuário pode ainda desenvolver seus próprios modelos utilizando a linguagem de modelagem do sistema.[[Tr(end)]]

== Installation ==

=== Windows 95/98/Me/NT4/XP ===

[wiki:Download] the installation package '''emso-win32-<version>.exe''' and just follow the steps of the guided setup.

NOTE: in order to run samples which need thermo-physical properties prediction, install VRTherm DEMO from http://www.vrtech.com.br.

=== Linux ===

[wiki:Download] the installation package '''emso-linux2-<architecture>-<version>.tar.gz''' and extract it with the following
command (considering architecture=i386 and version=0.9.50)

{{{
$ tar xzvf emso-linux2-i386-0.9.50.tar.gz
}}}

The above command will extract emso to the current directory, the executable is under the '''bin''' directory.

NOTE: currently only [http://www.ubuntu.com Ubuntu Linux] version 7.04 is supported, you will need the following additional packages:
 * refblas3 or atlas3-(optimized for your machine)
 * libumfpack4
 * libfox-1.4
