Hi,


Thanks a lot for ur hint.

Second, where do you write your data ?
I don't see anything in your fortran code before the close statement.

hint: you have to write your data as big endian, with VTK legacy format.

Please look at http://www.*vtk*.org/pdf/*file*-*format*s.pdf

Cheers,

Fisrt, please answer to the list.
