Software

Nowadays, topology optimization has emerged as a powerful and useful tool for the design of structures, also exploiting the ever growing computational speed and power. The design process has also been affected by computers which changed the concept of form into the concept of formation and the emergence of digital design. Topology optimization can modify existing designs, incorporate ex- plicit features into a design and generate completely new designs.

The liteITD program has been developed by Mariano Victoria, Osvaldo M. Querin, Concepción Díaz and Pascual Martí. LiteITD uses the ITD method (Isolines Topology Design method), in which, the topology and the shape of the design depend on an iterative algorithm, which continually adds and removes material depending on the shape and distribution of the contour isolines.

This graphical interface of liteITD allows to show how topology optimization can be used as a digital tool. The purpose of liteITD (lite version of Isolines Topology Design) software is to provide a tool for topology design. The liteITD program solves the topology optimization of two-dimensional continuum structures using von Mises stress isolines under single or multiple loading conditions, with different material properties in tension and compression, and multiple materials.

The liteITD program is fully implemented in the MATrix LABoratory (MATLAB) software environment of MathWorks under Windows operating system. GUIDE (Graphical User Interface Development Environment) was used to create a friendly Graphical User Interface (GUI). The usage of this application is directed to students mainly (educational purposes), although also to design-ers and engineers with experience.
