pyNastran v1.3.4 has been released (2022/5/30)

This is a a bug fix release mainly to address dependency changes:

  • support for nptyping 1.1.1-2.0 (removed as a required dependency)
  • support for h5py >3.0
  • GUI is compatible with PyQt5/6 and PySide2/6 and VTK 7-10
  • support for NX 2019.0, 2019.1

There are also at least 33 bugs fixed and a few features added from the 1.4 release (e.g., pathlib support, subcase limiting in the flutter F06 parser).

Additional minor changes (e.g., support for CFAST/PFAST in bdf_convert) were
added when fixing bugs.

Overall:

  • typing
  • cleaner setup.py files / packages.py

BDF:

  • bug fixes:
    • renaming pyNastran/nptyping.py to pyNastran/nptyping_interface.py to avoid namespace conflicts
    • require that nastran_format is a string
    • FORCE2/MOMENT2: fixed g4 bug (can't be blank)
    • FLUTTER: method can be string_or_blank (default='L')
    • FLUTTER: fixing EAS sorting bug in make_flfacts_mach_sweep (mach should be sorted to give sorted EAS)
    • MTRANS now supported for SOL 200 (vs only MTRAN; they're the same)
    • SET1: (and more generally any card that has 1,THRU,10 or 1,THRU,10,BY,2) now supports blank values
    • MATT1: g11_tid=0 update to None if it's 0
    • MATT3: table_ids update to None if they're 0
    • PARAM, DRESP1, DVCRELx now supports numpy int/floats
    • PARAMs: better type checking
    • PLOAD2: correcting number elements allowed
    • PLOAD4: surf_or_line, line_load_dir set to blank when they're default (to fix NX issue)
    • PBARL/PBEAML: I2 for BOX section
    • PBARL: fixed I1 bug
    • PBARL: I12 now returns I12 instead of [A, I1, I2, I12]
    • AUTOSPC (from case control) now works in bdf_renumber
    • BCTSET: fixing bug where defaults were mishandled (poor documentation in QRG)
    • DEQATN: better builtin handling
    • DMIG: better size/is_double handling
    • large field solid writing (forgot the *)
    • deepcopying a card now supports comments
    • Subcase: add_op2_data supports OUG1F
    • test_bdf: fixed bug when subcase=0 was the only subcase

    • PCOMP/G: layers must now be the same
    • PCOMP: added get_material_ids(include_symmetry=True), get_thetas(include_symmetry=True), get_souts(include_symmetry=True) methods
    • PCOMPG: added get_global_ply_ids(include_symmetry=True) in addition to PCOMP methods
    • CAERO1/2: added aefact_ids property
    • mesh_utils:
      • get_oml:
        • CTRIA6/CQUAD8/CQUAD support
        • applying np.clip to get_oml (to account for cos out of range precision issues)
      • collapse_bad_quads: now removes degenerate quads
      • bdf_mirror:
        • solid support
        • correcting case where eid_offset isn't calculated
        • fixed bug where tolerance was ignored
      • bdf_convert now supports:
        • CFAST/PFAST
