[Paraview] Plot3D

[Paul Adams]

I am on travel right now, otherwise I would be happy to help you.  My first
guess to this is that ParaView is getting confused between the XMol Molecule
files and Plot3D.

My second guess is that ParaView is not liking the Fortran Binary Plot3D
file.  Otherwise it looks like you are writing it out correctly.

You can write C binary VTK files directly from Fortran using the latest
gfortran compiler. For example, suppose I have a rectilinear grid, and I
wish to write out a scalar field called Fraction.

!......................................................................
!.....Write out Grid File in VTK format
!......................................................................
        open(11,file=solnfn,access='stream',status='new',convert=
'big_endian')
        write(11) "# vtk DataFile Version 3.0"//char(10)
        write(11) "Insert Comment Here"//char(10)
        write(11) "BINARY"//char(10)
        write(11) "DATASET RECTILINEAR_GRID"//char(10)
        write(ss,fmt='(A10,3I5)') "DIMENSIONS",ni,nj,nk
        write(11) ss//char(10)
        write(ss,fmt='(A13,I6,A6)') "X_COORDINATES",ni," float"
        write(11) ss//char(10)
        write(11) (x(i),i=1,ni)
        write(ss,fmt='(A13,I6,A6)') "Y_COORDINATES",nj," float"
        write(11) char(10)//ss//char(10)
        write(11) (y(j),j=1,nj)
        write(ss,fmt='(A13,I6,A6)') "Z_COORDINATES",nk," float"
        write(11) char(10)//ss//char(10)
        write(11) (z(k),k=1,nk)

        write(ss,fmt='(A10,I15)') "POINT_DATA",ni*nj*nk
        write(11) char(10)//ss//char(10)
        write(11) "SCALARS Scalar_Name float 1"//char(10)
        write(11) "LOOKUP_TABLE default"//char(10)
        write(11) f


All that is left to do then is to compile it with the following command:

gfortran -o 2vtk 2vtk.f90 -fconvert=big-endian -frecord-marker=4
