Hello,

I'm not familiar with all of the plugins in paraview, but I am wondering wh=
ether I need to write lower order elements in my vtk files for flexibility.

All of my data is point based.

I am thinking that:

if 1d:
    Write Lines
if 2d:
    Write Triangles
if 3d:
    Write Tetrahedron

Would there be any reason to write lines and triangles in 3d to the output =
file?

Thanks,

Juan

<FONT FACE=3D"Calibri, Verdana, Helvetica, Arial"><SPAN STYLE=3D'font-size:=

edron, then your output should contain four points and the topology for the=
 one tetrahedron. &nbsp;The topology of the four triangular faces is implic=
it in the topology of the tetrahedron. &nbsp;Including them explicitly woul=

Can you clarify it?<BR>
<BR>
Are you perhaps asking if you need to write out, for example, the triangle =
faces of each tetrahedron you write out? =A0(Answer: no.) =A0Are you asking=
 if you can define a point, line, or triangle in 3D space? =A0(Answer: yes.=

Hello Ken,<BR>
<BR>
I was asking the first question.=A0 I implemented the vtk file format for a=
n unstructured grid using:<BR>
type 10 elements for 3D (tetrahedra)<BR>
type 5 elements for 2D (triangles)<BR>
type 3 elements for 1D (lines)<BR>
<BR>
Each of these elements are defined in terms of points.<BR>
<BR>
My data only exists on points (point data).<BR>
<BR>
Is there any reason why I would want to put the lower dimensional elements =
in my vtk file in addition to the highest dimensional elements?=A0 <BR>
