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.


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

Target Audience

CAE Engineers, Mechanical Engineers including Automotive Engineers, Aerospace Engineers, and other subdisciplines, Mechanical Design Engineers, Students, and academic researchers.

Teaching Method

Lectures and computer practical sessions to validate acquired knowledge.

Learning Outcome

Following completion of this course, you will be able to:

  • Use LS-TaSC to determine optimal material distribution in a structure.
  • Setup and solve nonlinear topology optimization problems using LS-DYNA.
  • Apply topology optimization concepts to constrained, multi-load case, and multidisciplinary problems.
