# Computer Aided Engineering Topics

**2D**- Having both width and length, but no thickness.
**3D**- Having length, width, and thickness i.e. space.
**Boolean Operation**- Command that allows the addition, subtraction or intersection of solid objects in CAD.
**Computer Aided Engineering Books**- Lists all Computer Aided Engineering Books in the Encyclopaedia
**Computer Aided Engineering Weblinks**- Lists all Computer Aided Engineering Weblinks in the Encyclopaedia
**Fatigue Analysis**- The anlysis of a particular design to understand how durable it will be over it′s lifetime.
**G-Code Programming**- Programs written to operate NC machines with control systems that comply with the ANSI/EIA RS-274-D-1980 Standard.
**Modelica**- Open modelling language that supports expression=expression rather than just variable=expression
**Modeling**- A simplification of the real-life object and situation that preserves their essential nature, and allows a solution using mathematics.
**Monte Carlo Calculations**- Simulation based upon events that happen randomly, and so the outcome of a calculation is not always absolutely predictable.
**Navier Stokes Codes**- Computer software that contains the mathematical equations of motion for a viscous fluid.
**Numerical Analysis**- The study of methods for approximation of solutions of various classes of mathematical problems including error analysis.
**Numerical Control**- Any controlled equipment that allows an operator to program its movement by entering a series of coded numbers and symbols.
**One Dimensional**- Having length, but no width e.g. a line.
**Ray Tracing**- The calculation of the propagation, reflection and refraction of rays from source to receiver. This technique is used extensively within the optics and acoustics industry.
**Static Condensation (Guyan Reduction)**- A Finite Element reduction technique which is used in the dynamic solution of very large problems.
**Three Dimensional**- Having length, width, and thickness i.e. space.
**Two Dimensional**- Having both width and length, but no thickness.
