Summary0005331: Extract CTH Parts filter very slow - Too many ERROR messages from vtkExtractCTHPart.cxx, line 750
DescriptionOpen a CTH file (I tried 3D AMR).

Apply Extract CTH Parts filter and get tons of messages, which significantly slows the filter operation. This is especially bad with large data:

ERROR: In /usr/local/viz/paraview/src/ParaView/3.0.2/ParaView3/VTK/Parallel/vtkExtractCTHPart.cxx, line 750
vtkExtractCTHPart (0xc3d7d68): Volume fraction arrays are different type. They should all be float, double, or unsigned char

 Dave Karelitz had this to say, which might be important for whoever works on this issue:

"That actually seems like a bug in the reader. The reader's supposed to convert all the volume fraction arrays to unsigned char's. If it's only doing that for some, then that would introduce a tremendous amount of extra memory overhead."

 I think that the problem is that the SpyPlot reader makes sure that all of the arrays with names that start with "Material volume fraction" are either float or unsigned char, but the CTH Extract parts filter allows you to use any of the cell arrays. I will change the filter so that it only allows the user to choose from the arrays that start with "Material volume fraction" unless anyone objects. A more involved solution is to change the reader to indpendently decide what cell arrays are read and what ones are marked as volume fraction arrays, and then have the filter choose from any of the marked ones.

 I committed this change to the Server API and the GUI to enforce the requirement that all material arrays be of the same type.
