Modelica
Modelica is a language for modeling of physical systems, designed to support effective library development and model exchange. It is a modern language built
l d li ith th ti l ti d bj t i t d t ton a-causal modeling with mathematical equations and object-oriented constructs to facilitate reuse of modeling knowledge.
The use of Modelica are making Modeling of the dynamic behavior of technicalThe use of Modelica are making Modeling of the dynamic behavior of technical systems consisting of components from : mechanical, electrical, thermal, hydraulic, pneumatic, fluid, control and other domains in a convenient way.
These Models are described by differential, algebraic, and discrete equations.
