chrono::fsi::sph::FsiForce Class Reference

Description

Base class to calculate force between SPH particles.

This is an abstract class that defines an interface that various SPH methods should implement. The class owns a collision system fsi which takes care of GPU based proximity computation of the particles. It also holds a pointer to external data of SPH particles, proximity data, parameters, and numbers.

CopySortedToOriginal_Invasive_R3()

static void chrono::fsi::sph::FsiForce::CopySortedToOriginal_Invasive_R3 ( thrust::device_vector< Real3 > &  original, thrust::device_vector< Real3 > &  sorted, const thrust::device_vector< uint > &  gridMarkerIndex  )

static

Copy sorted data into original data (real3).

This function copies the data that are sorted in the collision system, into the original data, where data is real3. The class is invasive, meaning that the sorted data will be modified (and will be equivalent to the original). Therefore, this function should be used whenever sorted data is not needed, but efficiency is preferred.

CopySortedToOriginal_Invasive_R4()

static void chrono::fsi::sph::FsiForce::CopySortedToOriginal_Invasive_R4 ( thrust::device_vector< Real4 > &  original, thrust::device_vector< Real4 > &  sorted, const thrust::device_vector< uint > &  gridMarkerIndex  )

static

Copy sorted data into original data (real4).

This function copies the data that are sorted in the collision system, into the original data, where data is real4. The class is invasive, meaning that the sorted data will be modified (and will be equivalent to the original). Therefore, this function should be used whenever sorted data is not needed, but efficiency is preferred.

CopySortedToOriginal_NonInvasive_R3()

static void chrono::fsi::sph::FsiForce::CopySortedToOriginal_NonInvasive_R3 ( thrust::device_vector< Real3 > &  original, const thrust::device_vector< Real3 > &  sorted, const thrust::device_vector< uint > &  gridMarkerIndex  )

static

Copy sorted data into original data (real3).

This function copies the data that are sorted in the collision system, into the original data, where data is real3. The class is non-invasive, meaning that the sorted data will not be modified. This comes at the expense of lower efficiency.

CopySortedToOriginal_NonInvasive_R4()

static void chrono::fsi::sph::FsiForce::CopySortedToOriginal_NonInvasive_R4 ( thrust::device_vector< Real4 > &  original, thrust::device_vector< Real4 > &  sorted, const thrust::device_vector< uint > &  gridMarkerIndex  )

static

Copy sorted data into original data (real4).

This function copies the data that are sorted in the collision system, into the original data, where data is real4. The class is non-invasive, meaning that the sorted data will not be modified. This comes at the expense of lower efficiency.

Initialize()

virtual void chrono::fsi::sph::FsiForce::Initialize ( )

virtual

Synchronize the copy of the data (parameters and number of objects) between device (GPU) and host (CPU).

This function needs to be called once the host data are modified.

Reimplemented in chrono::fsi::sph::FsiForceWCSPH, and chrono::fsi::sph::FsiForceISPH.
