Handling of Paths for SrvD UserSubs Input Files
Browse files Browse the repository at this point in the history 
@rdamiani pointed out in issue #2059 that the existing method for handling file paths with `UserSubs` is difficult as it requires putting all the user input files in the same location as the ServoDyn file.  This commit is from recomendations from @rdamiani for a method he has had good success with.
