chrono::fsi::ChSystemFsi Class Reference

## Description

Physical system for fluid-solid interaction problems.

This class is used to represent fluid-solid interaction problems consisting of fluid dynamics and multibody system. Each of the two underlying physics is an independent object owned and instantiated by this class. The FSI system owns other objects to handle the interface between the two systems, boundary condition enforcing markers, and data.
