---|
22 | \param[in] gridDestGlobalDim global size of each dimension of grid source (all dimension must have the same size except of the one on which transformation is performed) |
---|
23 | \param[in] gridSrcGlobalDim dimension size of source grid (it should share the same size for all dimension, maybe except the domain on which transformation is performed) |

24 | \param[in] globalIndexGridDestSendToServer global index of grid destination on the current client to send to server |

25 | \param[in] localIndexGridSendToServer local index of grid destination on the current client to send to server |

26 | \param[in/out] globaIndexWeightFromDestToSource mapping between transformed global index of grid destination |

27 | and the weighted value as well as global index from grid index source |
