(MARS-normal) Add ability to open/concat multiple CTH restarts
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When running large CTH jobs, the user often ends up with multiple sets of restart files.
One way to do this is to specify a casefile containing the sets of restart files (sort of like a casefile of casefiles).
The other issue with CTH restart files is that not all the timesteps from each set are valid.
To address this, the reader should provide a hierarchical list widget with each set as a top-level item, and the timesteps that set provides as sub items. The user would then be able to activate/deactivate timesteps from a given set by checking or unchecking the box associated with that timestep.
set1 0 1 2 3 set2 2 3 4
The last item having to do with this is the ability to add sets to an existing CTH reader. So if the user's opened one set, there's an easy way to add another set to the same reader (and have it appear in the hierarchical timestep list).
