Errors while reading case-data in standalone launch mode

[mkundu1]

I'm seeing 2 different errors while reading case-data in standalone launch mode:

1. I have elbow.cas.h5 and elbow.dat.h5 in pwd.

>>> import ansys.fluent.core as pyfluent
>>> solver = pyfluent.launch_fluent()
>>> solver.file.read_case_data(file_name="elbow.cas.h5")

shutil.SameFileError: 'elbow.cas.h5' and 'D:\\ANSYSDev\\PyFluentDev\\pyfluent\\elbow.cas.h5' are the same file

2. I don't have elbow.cas.h5 and elbow.dat.h5 in pwd. They are in d:\work.

>>> import ansys.fluent.core as pyfluent
>>> solver = pyfluent.launch_fluent()    
>>> solver.file.read_case_data(file_name=r"D:\work\elbow.cas.h5")

Error 2 goes away if I copy d:\work\elbow.dat.h5 to pwd and execute read_case_data again.

Both of these were working before and work in pyconsole. I think it is better to avoid the file-transfer service in standalone launch mode for now.
