I am new to this part of ParaView sorry - the approach I took was to use read the data and use VTK for writing the files - you can start with the VTK examples and then plug in your values. There could be bugs so start small and grow the problem size. I also found that including the rendering from the VTK examples made things quicker as you could write/read and test in the same code.

Paul, This is a good guess. I have played with this already and Paraview would read the points okay (for big ended write), but it would crash when reading the cell data: . for k=1:length(Connectivity) f=Connectivity{k}; ctype=zeros(size(f, 1),1)+Cell_types{k}; fprintf(fid,'CELLS %d %d\n',size(f,1),(size(f,1)*(size(f,2)+1)));% if (~binary) for i= 1:size(f, 1) fprintf(fid,'%d ',size(f,2)); for j= 1: size(f,2) fprintf(fid,'%d ',f(i,j)-1); end fprintf(fid,'\n'); end else fwrite(fid,cast([zeros(size(f,1),1)+size(f,2),f-1],'int32'),'int32','b'); end fprintf(fid,'\n'); fprintf(fid,'\n'); fprintf(fid,'CELL_TYPES %d\n',size(f,1));% if (~binary) for i= 1:size(f, 1) fprintf(fid,'%d\n',ctype(i)); end else fwrite(fid,cast(ctype,'int32'),'int32','b'); end fprintf(fid,'\n'); fprintf(fid,'\n'); end . There is something wrong in the code above (or there's a bug in paraview). By the way my Matlab code that writes out binary *structured_grid* data works just fine with paraview. It is just the unstructured grid that's giving me headaches.

I think there is a VTK util on the MATHWORKS site but I haven't tried that.

Hi, Did you ever get the Matlab writing of the binary VTK files to work? I'm having problems with them too: PV crashes when reading the binary files.
