This permits acausal modeling that gives better reuse of classes since equations do not specify a certain data flow direction. The four most important features of Modelica are: 1) Modelica is based on equations instead of assignment statements.

Modelica is also an object-oriented equation based programming language, oriented towards computational applications with high complexity requiring high performance. for the purpose of computer simulation of dynamic systems where behavior evolves as a function of time. Modelica is primarily a modeling language, sometimes called hardware description language, that allows you to specify mathematical models of complex physical systems, e.g.

The goal with the OpenModelica effort is to create a comprehensive Open Source Modelica modeling, compilation and simulation environment based on free software distributed in binary and source code form for research, teaching, and industrial usage. Its long- term development is supported by a non-profit organization the Open Source Modelica Consortium (OSMC). OpenModelica is an open-source Modelica- based modeling and simulation environment intended for industrial and academic usage. Compared to OpenModelica there are several drawbacks for Simulink, they are 1) Simulink does not have a standardized graphical notation.2) Simulink is based on the signal-oriented paradigm which always forces a causal dependence between inputs and outputs of a block when solving equation systems.3) SimulinkР”Вoes not support inheritance-concepts for classification of components in order to enable their reuse. Simulink is most commonly used in control theory and digital signal processing for multi domain simulation and Model-Based Design. Simulink is a block diagram environment for multi domain simulation and Model- Based Design. Simulink, developed by MathWorks, is a commercial tool for modeling, simulating and analyzing multi-domain dynamic systems. Mathematical Modeling and Simulation of a boiler using Simulink is an existing work. After instantiating the models can be simulated and the results plotted as a chart. The OpenModelica environment is a collection of tools, called OpenModelica Tools, to create a complete Modelica model. The goal is to create a complete modeling and compilation and simulation environment based on free software distributed in source code and executable form which is intended for use in research, teaching, and industry. Openmodelica is an open source Modelica environment developed and supported by Linkoping University and the Open Source Modelica Consortium (OSMC).Modelica is a language for modeling of complex physical systems such as Robotics, Aircrafts, Satellites etc.The OpenModelica environment consists of several interconnected subsystems. Simulation experiments are carried out based on the nominal values of system variables and parameters collected from a BHEL, 210MW Boiler. The subsystem models are then integrated to obtain a full-fledged integrated The subsystem models are :Boiler furnace model, Boiler drum model, Primary superheater model, Attemperator model and Secondary superheater model. From modeling point of view, the boiler is divided into five subsystems and for each subsystem, mathematical models are developed based on the modeling principles and the knowledge gained during the boiler system study. The model is based on physical principles and has a number of parameters, most of which are determined from construction data and few of them from field test data. The goal is to develop a model that captures the key dynamical properties of the boiler over a wide operating range. Keywords: Modelica, OpenModelica, Simulink, Modelica is also an object- oriented equation based programming language. Openmodelica is an open source Modelica environment developed and supported by Linkoping University and the Open Source Modelica Consortium (OSMC). Modelica is a new generation Modeling language. In order to explore the details about modeling and simulation of a boiler, Simulink and OpenModelica are used. Particular attention has been devoted to model the boiler furnace dynamics well, because power plant modeling experts have been successively neglecting the boiler furnaces in their attempts due to the complexity in modeling and non-availability of proper measurements for furnace variables. S.I.S.T., is the representation of the behaviour of a real process through the resolution of a mathematical model. Design and Simulation of an Efficient Power Plant Boiler Using OpenModelica
