tem_opVar_setupIndices Subroutine

public recursive subroutine tem_opVar_setupIndices(fun, varSys, point, offset_bit, iLevel, tree, nPnts, idx)

This subroutine call setup indices of input_variable

the interface has to comply to the abstract interface tem_varsys_module#tem_varsys_proc_setupIndices.

Arguments

Type IntentOptional Attributes Name
class(tem_varSys_op_type), intent(in) :: fun

Description of the method to obtain the variables, here some preset values might be stored, like the space time function to use or the required variables.
type(tem_varSys_type), intent(in) :: varSys

The variable system to obtain the variable from.
real(kind=rk), intent(in) :: point(:,:)

List of space coordinate points to store as growing array in method_data
character, intent(in), optional :: offset_bit(:)

Offset bit encoded as character for every point.

Offset integer coord(3) is converted into a character with offset_bit = achar( (coord(1)+1) + (coord(2)+1)4 + (coord(3)+1)16 ) Backward transformation form character to 3 integer: coord(1) = mod(ichar(offset_bit),4) - 1 coord(2) = mod(ichar(offset_bit),16)/4 - 1 coord(3) = ichar(offset_bit)/16 - 1

If not present default is to center i.e offset_bit = achar(1+4+16)
integer, intent(in) :: iLevel

Level to which input points belong to
type(treelmesh_type), intent(in) :: tree

global treelm mesh info
integer, intent(in) :: nPnts

Number of points to add in method_data of this variable
integer, intent(out) :: idx(:)

Index of points in the growing array and variable val array. Size: nPoints

This must be stored in boundary or source depends on who calls this routine. This index is required to return a value using getValOfIndex.
