Import the estimated error and store it in the data structure of the
The first token of each line is the element identifier, the second token
the error. However, the element id is ignored.
The line number of the input file has to correspond
with the position of the element in the list of elements. The error in the first
line is stored in the first element in the list that was not refined and
therefore belongs to the finest triangulation. The error in the second
line is stored in the second element in the list that was not refined,
and so on. This is exactly the order in which the quadruplets of vertex ids
were stored by
expelement and which has to be preserved. Consequently
the grid must not be manipulated between the execution of
If the number of lines is smaller than the number of elements contained in the
finest triangulation, a warning will appear in the text window.
