ParaView is now failing on Alegra output with ParaView 6.1.0. Note that I believe Alegra hasn't updated their writer to IOSS, so are still using the Exodus library for writes. This dataset opens properly with 6.0.1. Dataset is UUR, I will try to add it here. Here is how to replicate: * 6.1.0, builtin, Linux * Open sphereImpact.exo.4.*. Apply. Nothing shows on the screen. Error message is: ( 46.009s) [paraview ] vtkIOSSReader.cxx:478 ERR| Error reading entity block (or set) named 'block_1' from '/snip/ sphereimpact.exo'; skipping. Details: ERROR: For field named 'entity_processor', code requested value of type 'integer', but field type is '64-bit integer'. Types must match @spiros.tsalikis @cory.quammen
