Introduction to Ansys LS-TaSC


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.

Learning Outcome

Following the 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.
  • Optimize a surface to minimize stress concentration.


  • 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 Options: Training materials for this course are available with a Ansys Learning Hub Subscription. If there is no active public schedule available, private training can be arranged. Please contact us.
