FSI module


Fluid-Solid Interation modeling and simulation.

This module provides support for modeling multi-phase systems for fluid-soild interaction problems and granular-solid interaction problems. When compiling this library, remember to define CH_API_COMPILE_FSI (so that the symbols with 'CH_FSI_API' in front of them will be marked as exported). Otherwise, just do not define it if you link the library to your code, and the symbols will be imported.

Collaboration diagram for FSI module:


 Physics objects
 Physics objects for the Chrono::FSI module. Including the fluid dynamics system, force system, interface with Chrono core module, simulation parameters, and data structures.
 Collision objects
 Collision objects handles the neighbor particle searching in Chrono::FSI module.
 Linear solvers
 Class for solving a linear linear system via iterative methods. Only works when I2SPH or IISPH is set to solve the fluid dynamics.
 Modeling utilities
 Handles utilities including creating BCE particles, setting parameters via a JSON file, and output data into files with specified format.
 Math utilities
 Math utilities for the Chrono::FSI module. These functions can be invoked either on the CPU (host) or on the GPU (device)
