What is it about?
A new approach for the numerical modelling of a rigid solid moving in a multiphase flow is presented. The method is capable to solve the dynamics of the solid and the main features of the fluid at a very low computational cost and with a very high degree of accuracy.

Why is it important?
Rigid body motion in a viscous fluid is a hot issue in engineering (Civil Engineering, Renewable Energy Engineering, Marine Engineering, Aeronautics, etc) but it is also paramount to understand several natural processes of relevance in Geosciences, Planetary Sciences and Astronomy.
Perspectives
We hope this work will open the path to a new way of approaching the solid-fluid interaction, without the need for extremely fine meshes and days/weeks of computational time.
