The Gaea csv library reference is out!

The so-called CSV (Comma Separated Values) format is the most common import and export format for spreadsheets and databases. A CSV file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. In Gaea , the csv module implements functions to read and write tabular data in CSV format.

Please, check out the csv library reference here .

Examples of using the package are given here .

In practical engineering, there is always the need of predicting the response of a structure or mechanical system under external forcing in order to isolate a sensitive system from vibrations or design the system in such a way as to withstand the induced vibrations. The response of a building or bridge under wind or earthquake loading, the response of an engine on mounts or the suspension of a car are typical examples of such cases. The most common form of external forcing applied on a mechanical system is the harmonic excitation.

Gaea can be a very useful tool for the analysis...

In the analysis and design of oscillating systems there are often times when a specific type of ocsillation design is desired in order to achieve a desired response effect. This procedure usually requires the analysis of a simplified model of the oscillating system in order to understand the underlying dynamics and be able to trigger or muffle certain characteristics. One very common parameter that is needed to be tuned in such systems is the amount of damping.

Damping in an oscillator, is responsible of slowing down the motion of the system, by substracting amounts of energy...

Gaea is a great tool not only for computational engineering, but for educational purposes as well. The straight-forward evaluation of mathematical formulas combined with the easy to use plotting capability of Gaea, can enable students to get a better understanding on the physical interpretations of mathematical equations that describe physical systems.

In this particular example, a simple one degree of freedom harmonic oscillator is analysed and the free vibration response is plotted using Gaea . The mathematical modelling of the 1 dof oscillator is usually done using the...

While searching for a quantitative description of physical phenomena, the engineer establishes a system of ordinary or partial differential equations — valid in a certain region (or domain) — and imposes on this system suitable boundary and initial conditions. A partial differential equation (PDE) is an equation, involving an unknown function of two or more variables and certain of its partial derivatives. A PDE can be solved numerically with various methods, such as finite difference method, finite volume method, finite element method, spectral method, meshfree method, domain...
