area<BR></FONT><BR></DIV>
<DIV></DIV>Hello,<BR><BR>Thanks for your reply.Actually paraview crashes when I
do integrate variables.And I don't know how to use python scripting in
paraview.So if you give me the script and tell me how to run it, that would be
great.I found area of the triangles by using python calculator.I wrote in the
expression box : area(input[0]) and select cell type data.After that it gives me
some number beside every cell.As I sum all the results (which i beleive the area
of my triangles) I got the result which is very close to my expectation.Is
area(input[0]) expression giving me the area of all the triangles? or what?I
found this expression in wikipedia I guess.Thank you a lot.I think for
people like you paraview is getting popular day by day.<BR><BR>

pretty sure you can use a Python programmable filter to do this. If
you<BR>check the doxygen for vtkTriangle, there should be a member function
that<BR>returns the area of a specific triangle. Otherwise, the area of a

Hello,<BR>><BR>> I have created a surface using the delaunay2d
filters.After creating<BR>> the surface I use smooth filter for surface
smoothing.Now I want to<BR>> find the surface area created by paraview.How
can it be possible?I am<BR>> trying to use the integrate variables but I am
not sure about this<BR>> filter because when I select this filter paraview
crashes.Or is there<BR>> any way I can get the area of the triangles of my
delauny<BR>> filters?Cause if I go to the delaunay filter and change
table<BR>> attribute to cell it shows the cell ID and highlights only
that<BR>> triangle in the model but it doesn't show the area of the
triangle.I am<BR>pretty new in paraview.Could you please help?<BR>><BR>>
