[vtkusers] Problem with vtkDataSetWriter

[Stevan Dubljevic]

Dear all,
I have a code that work OK on my vtk-5.0 installation on one machine
however the sam code does not compile at another where I installed vtk-5.1
...

however I installed vtk-5.0 also hoping that will work but it gives me an
error ...
problem is in vtkDataSetWriter .... the last two commands are giving error
..

I read vtk file then I applay filter to make entire grid into tetrahedra
and then I threshold to get mesh that I used for FEM  ....

However I started having problems .... with vtkDataSetWriter ....

I belive that there is some kind of trick that can fix this ..... or I am
making some error .. but the same code used to work on other machine .....

Please if you have any hint ....
Thanks a LOT


Here is a code ......
