Introduction to LS-TaSC


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


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.
