Moving particle simulation (MPS) method can be applied in a two-stage simulation in computer aided engineering to resolve fluid structure interaction problems for industrial design. In this technical article, we demonstrate how to apply a one-way coupling technique using a combination of ParticleWorks and LS-DYNA to estimate tsunami damage to a vehicle.
This technique can be used for resolving problems with incompressible fluid dynamics in various industries in the product design, development and manufacturing phases.
In the first stage of this simulation, we create the vehicle as a rigid body particle cluster, calculate the pressure distribution on the particle structure and map it on the STL vertexes to obtain the pressure history, which is converted into pressure load for the second stage of the simulation.
In the second phase, we obtain the deformation and stress distribution on the vehicle from both the impact of the tsunami and the vehicle’s consequent impact with the nearby wall.

CASE STUDY
The Extremely Large Telescope (ELT) is a 40m-class optical and infrared telescope being built in Chile. The ELT has a complex geometry, with a rotating structure and a dome that must be protected from wind effects to ensure accurate observations. To study the wind flow within the dome, a computational fluid dynamics (CFD) model was created.
