Smooth Particle Hydrodynamics Method
in Ansys LS-DYNA

Course Overview

This class provides engineers and researchers with the fundamental theoretical background on the smoothed-particle hydrodynamics (SPH) formulation. It also overviews applications of SPH to different industrial problems in defence, aerospace, automotive and consumer products. The class emphasizes which SPH formulation is suitable for various applications including fluid and solid materials. To illustrate different SPH features, the class includes a workshop with around 30 LS-DYNA input examples covering all keywords and contact entities. Contact between SPH and FEM parts and also between different SPH parts will be illustrated in 3D, 2D, and 2D axisymmetric problems. A workflow for setting up an SPH problem in LS-PrePost will also be discussed.

Learning Outcome

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

  • Understand the SPH theory, its advantages, and limitations, with a strong focus on applications in aerospace and defence industries. 
  • Set up an SPH model to study high-deformation phenomena, such as bird strike or high-velocity impacts. 
  • Leverage advanced capabilities such as SPH-FEM coupling and adaptivity, thermal coupling, or fluid-specific formulations, to accurately and efficiently model complex scenarios. 
  • Postprocess SPH results and extract valuable results from the simulation.
