Introduction to
Ansys LS-TaSC

Course Overview

This class provides an introduction to using the topology optimization and shape computation code, LS-TaSC, for design. It covers both the theoretical concepts and practical aspects of topology optimization. The course includes workshop sessions in which the theoretical topics are applied. The LS-TaSC graphical user interface is used to teach input preparation and post-processing.

Prerequisites

  • Equiv­a­lent knowl­edge to an in­tro­duc­to­ry class in LS-DY­NA is rec­om­mend­ed.

Teaching Method

Lectures and computer practical sessions to validate acquired knowledge.
