Preprocessor (CAE)
Appearance
In Computer aided engineering (CAE) a preprocessor is a program which provides a Graphical user interface (GUI) to define physical properties. This data is used by the subsequent computer simulation.
Hypermesh and ANSA are some of the preprocessors widely used, Preprocessor usually takes input files of CAD softwares and that CAD data is used to Represent continuous structure as a collection of grid points connected by discrete elements. Preprocessor softwares allow the user to
