Get Started

Ansys LS-DYNA® nonlinear dynamics structural simulation software is the market leader in explicit finite element programs, widely used for large deformation analysis. It also includes its own implicit solver capable of solving complex nonlinear structural problems. This course introduces the theoretical and practical background of Ansys LS-DYNA's implicit capabilities. It is designed for users who have prior knowledge and experience with Ansys LS-DYNA or extensive experience with other implicit solvers.

Learning Outcomes:

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

  • Utilize existing LS-DYNA models within your group, eliminating the need to convert models to different programming languages for implicit solution.
  • Potentially reduce software costs annually by leveraging the implicit solver capabilities within LS-DYNA.

Prerequisites:

  • Completion of Introduction to Ansys LS-DYNA Software course is required.

Please note: These training materials were developed and tested in the 2020R2 release.
