I think Mathieu presents a good, and much better, solution than we currently have.
How would the “user settings” be created/added/edited/deleted? Could we include site specific settings? Obviously, for Sandia I would like users to use the IOSS reader for CGNS files, but as per a previous conversation with Utkarsh, most general users will still just use the CGNS reader.
What does “use the selected reader” mean? For instance, I have the Exodus reader loaded, and I select can.exo. I use files of type: Specific Format. I haven’t selected a reader? Is this the previously selected reader?
Lets make this the complete list, including illegal readers. Sometimes ParaView thinks a reader is not possible, and won’t present it as an option. We want to try to read with that reader, to see what error messages it presents.
