evalLogicalLess_fromIndex Subroutine

public subroutine evalLogicalLess_fromIndex(fun, varSys, time, iLevel, idx, idxLen, nVals, res)

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.
type(tem_time_type), intent(in) :: time

Point in time at which to evaluate the variable.
integer, intent(in) :: iLevel

Level on which values are requested
integer, intent(in) :: idx(:)

Index of points in the growing array and variable val array to return. Size: nVals
integer, intent(in), optional :: idxLen(:)

With idx as start index in contiguous memory, idxLength defines length of each contiguous memory Size: nVals
integer, intent(in) :: nVals

Number of values to obtain for this variable (vectorized access).
real(kind=rk), intent(out) :: res(:)

Resulting values for the requested variable.

Dimension: n requested entries x nComponents of this variable Access: (iElem-1)*fun%nComponents + iComp
