We can read files in a better way (so that relative paths are correctly resolved). See e.g. https://github.com/4C-multiphysics/4C/blob/main/src/inpar/4C_inpar_solver.cpp#L104-L108

This places the xml file into the top level directory of all xml files for solvers/preconditioners. There is an existing folder structure. @maxfirmbach, should we sort it into the folder structure? If yes, where? Into a new directory?

@dharinib98 @mayrmt We need to figure out a place, not sure where it fits best, in theory we could just create a folder called preconditioner and put all preconditioner related .xml files there with an updated naming scheme. So xml/preconditioner/ifpack.xml would work for me right now.

Yet another reason to use yaml for input files :)

yes, this is also the case with overlap values, not all files use a value of 0. Based on the number of tests that fail, we can think about a solution by maybe adding another xml file for the higher gfill values

We can have one or two default xml files in the central xml file collection. If individual tests require a specialized preconditioned, then we can put the xml file just next to the input file.
