AB - A novel algorithm is proposed for the simulation of fluid-structure
interaction problems. In particular, much attention is paid to natural phenomena
such as debris flow. The fluid part (debris flow fluid) is simulated in the framework of the smoothed particle hydrodynamics (SPH) approach, while the solid
part (downstream obstacles) is treated using the finite element method (FEM).
Fluid-structure coupling is implemented through dynamic boundary conditions.
In particular, the software “TensorFlow” and an algorithm based on Python are
combined to conduct the required calculations. The simulation results show that
the dynamics of viscous and non-viscous debris flows can be extremely different
when there are obstacles in the downstream direction. The implemented
SPH-FEM coupling method can simulate the fluid-structure coupling problem
with a reasonable approximation.
