◆ Grid_moveParticles()

subroutine Grid_moveParticles ( real  dataBuf,
integer  propCount,
integer  maxCount,
integer  localCount,
integer, dimension(indexCount)  index_list,
integer  indexCount,
logical  coords_in_blk 

This routine deals with moving data associated with quantities such as particles or rays, which do not have a fixed association with a specific point of the domain all through the time evolution. As they change their association from block to block, this routine moves them to the correct block and processor. Depending upon whether the movement is due to re-gridding or not, this routine calls appropriate function to move the data as needed.

dataBuf : the data structure containing the data of interest It is two dimensional real array, the first dimension represents properties associated with the data structure, and second dimension is index to individual elements in the datastructure.

propCount : number of properties for this datastructure

maxCount : This is parameter determined at runtime, and is the maximum count of elements that a simulation expects to have. All the arrays are allocated based on this number localCount : While coming in it contains the current number of elements in the data structure mapped to this processor. After all the data structure movement, the number might change, and the new value is put back into it index_list : The list of fields in the incoming dataBuf, the list are used to make the indices of tag, block processor and physical location of each individual data item to the GridParticles subunit so it can move the concerned data item appropriately indexCount : The count of fields included in index_list

coords_in_blk : if true then this routine should not make assumptions about being able to determine the destination of a particle at the source processor. The matching of a particle to a block in this situation depends upon verifying that the position co-ordinates of the particle are within the bound box of the block
