Yes, unfortunately, currently the PLOT3DReader can only deal with
structured grids.

The vtkUnstructuedGrid format is not the same as the PLOT3D format.
You will have to manually (or by means of a program) convert your
PLOT3D files to the VTK format.  The VTK file format is documented
here:

So the solution is to, read the document carefully and convert your
PLOT3D file to a vtk file and then use vtkUnstructuredGridReader to
read in the file.

Hope this helps,
