pyyeti.nastran.op2.OP2.rdop2mats

OP2.rdop2mats(names=None, lower=False, verbose=False, which=-1)[source]

Read all matrices from Nastran output2 file.

Parameters:

  • names (list_like; optional) – Iterable of names to read in. If None, read all. These can be input in lower case. Each name in names can end in a “*” for simple wildcard matching.

  • lower (bool; optional) – If True, returned names will be in lower case.

  • verbose (bool; optional) – If True, print matrix names to screen as they are found.

  • which (integer or str; optional) – If integer, specifies which occurrence of each matrix to read starting at 0. Default is -1; read the last entry for each matrix only. Can also be the string “all”. In that case, each entry in the dictionary is a list of all occurrences of each matrix (even if there is only one occurrence).

Returns:

dict – Dictionary containing all matrices in the op2 file. If which is an integer:

{'NAME1': matrix1, 'NAME2': matrix2, ...}

If which is “all”:

{'NAME1': [1st matrix1, 2nd matrix1, ...],
 'NAME2': [1st matrix2, 2nd matrix2, ...],
 ...}

Notes

Unless lower is True, the keys are the names as stored in the op2 file (upper case).
