Hello Rick,<div><br></div><div>Can you please send me the file to me also(ASCII preferable)? I just finish building my own VTK parser which I believe has equivalent functionality at least for ASCII .VTK files. I also had some precision issues(and byte ordering) while writing a Binary parser. Certainly there are some files that Paraview cannot fully comprehend. Well, let me know.</div>

I'm going to guess that this is a precision issue - have you tried writing the files into single precision binary and trying again with Paraview? This won't matter for ASCII cases but makes the difference for Binary. The plot3d reader currently works only with single-precision.</div>
<div><br></div><div>Paraview does not support function files. You will need to modify the vtkMultiBlockPLOT3DReader (or write your own) + paraview plugin for that.</div><div><br></div><div>Da<br><br><div class="gmail_quote">

<div style="word-wrap:break-word">Yes, I have also generated an ASCII plot3D file, which I can get paraview to read. However, paraview does not correctly interpret the grid file. The geometry I create with my simple Fortran code is a cube. Paraview successfully reads both the ASCII grid and data files, but when I view it in paraview the geometry is incorrect. Tecplot does not have this problem with the same grid and data files. I am interested in any suggestions on the right combination of options to choose when reading this plot3D file into paraview, but I have not been able to find the correct combination of options to read a plot3D binary grid and data file. In addition, since paraview does not display the correct geometry when I have it read an ASCII version of the same grid and data plot3D files I believe there is more to this than just choosing the right options.<div>
<br></div><div>There are a number of different plot3D formats and I have tried reading a number of these into paraview, all with the same results.</div><div><br></div><div>Sincerely,</div><div>Rick</div><div><div></div>

When I open a Fortran generated plot3D file I select "plot3D" as the file type and then select the following three options: "binary file", "has byte count" and if needed "multigrid". I have tried various combinations of these options without success. I wrote a short and simple Fortran program to generate a small test plot3D grid file and data file, which I can successfully read with tecplot, but is not readable in paraview 3.6.1. Has anyone had success reading Fortran generated plot3D files with a recent version of paraview and if so, what plot3D format was used and what paraview file options were selected?<br>
<br> This is for paraview 3.6.1 on a mac running leopard. However, I run into the same problem on the windows version of paraview as well.<br> <br> Here is the error message I receive:<br> <br> ERROR: In /Users/kitware/ParaViewReleases/ParaView-3.6/ParaView3/VTK/IO/vtkMultiBlockPLOT3DReader.cxx, line 783<br>
