Estimation of tsunami damage to vehicles using simulation with Particleworks and LS-DYNA

MPS method in fluid computational dynamics offers possibilities for improving the design of vehicle safety

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.
