Reading HDF5 file using both h5py and tables

Python Help
1

I had had some success reading hdf5 files generated from MSC/Nastran using both h5py and tables. Now I’m trying to do the same with a file generated by Simcenter/Nastran and I’m having trouble because the data block includes a colon in the names.

This Syntax works using h5py:

hf=h5py.File(‘solidbeam-3prtfem-sol101.hdf','r')
myElm=hf['model']['geom2:elem_data']['geom2_chexa']

Typically I would try the following for tables:

hft=tables.open_file(‘solidbeam-3prtfem-sol101.hdf','r')
myElmTable=hft/model/geom2:elem_data/geom2_chexa

The : character in geom2:elem does not work.

The following syntax does work and prints item names as follows:

for obj in hft:
  print obj

/model/geom2:elem_data/geom2_chexa (Table(40,)) ‘’

Do you have any advice on how this data-block should be referenced in tables?
Any help will be greatly appreciated.

Assuming this is in your Python code, did you perhaps mean just myElmTable="hft/model/geom2:elem_data/geom2_chexa"? If you want a string, use quotes, just like everywhere else. With the code you’ve written, the : is a syntax error, and the / is a division operator.

Aside from that, I can’t understand the question, sorry.
