When having a failed analysis I find it pretty annoying that i have to click back and forth from the output file to the model tree to find the actual cause of the simulation failure.
This could be more easily resolved by opening up a dialog after a failed simulation listing all the Warnings and Failures that occured during the simulation (with a button "show in context" to know in which context of the nastran output it appeared).
And to be honest: Failures make analysis work so lenghty. It would be really nice to have a direct link to the Nastran Error Code Knowledge base to get hints on how to resolve the error on that same dialog as well.
