evaluate_first_spacetime_vectorByCoordinate Subroutine

public recursive subroutine evaluate_first_spacetime_vectorByCoordinate(fun, varSys, point, time, tree, nPnts, res)

This subroutine returns first spacetime function on overlapping regions fo given coordinate points for vectorial variable. Spacetime function are evaluated only on the coordinate which belong to st_fun shape.

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(:,:)

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

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
