Just happened across an application where EquationSystems::delete_system() might be quite useful, so I went to check the docs...
598 benkirk /**
598 benkirk * Remove the system named \p name from the systems array.
1812 roystgnr * This function is now deprecated - write the
1812 roystgnr * libmesh-devel mailing list if you need it reimplemented.
598 benkirk */
598 benkirk void delete_system (const std::string& name);
So here we are – 4,000 svn revisions later, the method is still in there and I’m dubious that it will work right if it is called.
Roy, do you happen to remember what led up to the deprecation?
I suppose asking the list to reimplement it would be an exercise in futility, but if we can figure out what the issues were I might be able to do something about it...
