0011622: Contour - Generate normals, gradients and scalars doesn't do anything
Local server, windows client, trunk.
Open disk_out_ref.exo.
Contour. I am contouring on temp, 400 degrees.
Select Generate Normals, Generate Gradients, and Generate Scalars. I don't see anything appear normal wise, gradient wise or scalar wise...

Those options only have effect on structured data. For unstructured data like disk_out_ref, a different internal algorithm is used. The unstructured data algorithm always generates scalars and normals but never gradients.

OK, that makes sense. But shouldn't the checkbox be grayed out then? Options that do nothing or don't work should not be available...

This behavior is still funky for multiblock datasets that have both structured and unstructured grids in them. All options are grayed out in the gui but the default of Compute Normals being checked and Compute Scalars not being checked is wrong for this since for the unstructured grids the normals aren't computed and scalars are.
