diagonal section and integration handling difficulties
Dear Ferreters,
actually working with a oceanmodel calculating stream intensitys it
occured to us to check the produced data by integrating the stream
components u (longitude direction) and v
(latitude direction) along any diagonal line in the datafield.
First question concerning is:
Is there a standard way of gaining the requested output? Or has there
been any programfile published yet to help us in this task?
And second:
During our calculation we come to a situation similar to the one in the
append lines.
We take the vertical section out of the original data file and reduce
the data to a 2 dimensional field (as you may see the depth ist
integrated already)
So all we need do to is to integrate the x-axis and we compute the
directed stream of water. The question is why do we gain correct output
for the integration with an existing y-axis and the wrong output for the
integration along the x-axis for the integration without y-axis? For
this is what occurs if we do not do a clear zonal or meridional section.
Any help is welcome
