Hello Thank you for the suggestion.
If I do this: Import ensight (that is multi-block) data->apply MergeBlocks filter-> Apply calculator filter (to get magnitude of the velocity data, volume rendering complains of lack of points otherwise). And then select volume as representation then I get a progressbar that says "OpenGLProjectedTetrahedraMapper: 1" that extremely slow, appears to get incremented by 1% every 5 minutes or so. Is this by design or a bug? I have tried it on 2 different computers. The data set used is a 80x80x46 point volume cube.
