Dear Richard, The DualSPHysics package (v5.0.5) available in its website ( https://dual.sphysics.org/downloads) includes several examples, in the folder *DualSPHysics/examples/chrono/12_ExternalVelocity*, of how to impose a motion to a prop by using external velocity. This package contains the coupling with Chrono as a precompiled library, which was generated from the source code of Chrono with several changes to allow DualSPHysics-Chrono coupling. There is a paper about this coupling that may be of interest: Martínez-Estévez, I., Domínguez, J. M., Tagliafierro, B., Canelas, R. B., García-Feal, O., Crespo, A. J. C., & Gómez-Gesteira, M. (2023). Coupling of an SPH-based solver with a multiphysics library. Computer Physics Communications, 283, 108581. https://doi.org/10.1016/j.cpc.2022.108581
