Modeling at mathematical level

Modeling at the mathematical level

A math model is built by inserting objects into an open document and then connecting some of them. Objects mostly appear as boxes with explanatory pictures and connections as lines between boxes. Objects can be of different types. The basic type is the equation object that represents a single NMF or Modelica component. Other types represent a boundary condition, or even a small subsystem (macro object). Some objects are mere graphical elements designed to make it easier to understand the structure of the entire system. Each IDA application can accept only those equation objects that are specific to the chosen application.
