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

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

Programmatics:

• supports Python 3.7-3.10
• 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

  • 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
  • test_bdf: fixed bug that dropped the global subcase
    • it's not used unless there are no local subcases
• added:
  • pathlib support
  • GRID: method get_position_wrt_coord_ref
  • MAT11: adding get_density
  • DVCRELx: CMASS/M and CELAS4/K options
  • DCONSTR: support for FLUTTER/PK
  • DRESP1: PBEAM/PBEAML, FATIGUE support
  • DRESP2: now references DNODE
  • DVMREL2: now supports MAT2, MAT8
  • 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
      • rho, area conversion f06 flutter:
• bug fixes:
  • supporting any number modes
  • correcting default for in/out_units (documentation error)
• added:
  • subcases support
  • vd_limit and damping_limit
• adding:
  • repr
  • mach, dynamic pressure, altitude plots

op2:

• pathlib support

op2 geom:

• PARAM: improved (PVT/PVT0 table) loading
• PSOLID: FFLUID support
• PSOLID: isop=2 support
• PCOMP: ft (failure theory) HFAI, HTAP, HFAB support
