The reason is simply to determine file type from suffix. I want to keep it (and it's been used in tons of examples, papers, books, tutorials). Ideally, one should be able to use either File or VTKFile (just as Matrix and PETScMatrix) and direct use of VTKFile could provide some extra features. -- Anders _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : [email protected] Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
