build_thru_float(packs, max_dv=None)
- pyNastran.bdf.cards.collpase_card.build_thru(packs, max_dv: int | None = None, nthru: int | None = None)[source]
Takes a pack [1,7,2] and converts it into fields used by a SET card. The values correspond to the first value, last value, and delta in the list. This means that [1,1001,2] represents 500 values. [1,1001,1] represents 1001 values and will be written as [1,THRU,1001]..
- Parameters:
- packslist[pack]
- packlist[int first, int last, int delta]
the first, last, delta id values
- max_dvint; default=None -> no limit
defines the max allowable delta between two values
- nthruint; default=None
don’t use this; it will crash
- Returns:
- valuevaries
the value of the field
- pyNastran.bdf.cards.collpase_card.build_thru_float(packs: list[list[int]], max_dv: int | None = None) list[int | str][source]
Takes a pack [1,7,2] and converts it into fields used by a SET card. The values correspond to the first value, last value, and delta in the list. This means that [1,1001,2] represents 500 values. [1,1001,1] represents 1001 values and will be written as [1,THRU,1001].
- Parameters:
- packslist[pack]
pack : list[first, last, delta] first, last, delta are integers
- max_dvint; default=None -> no limit
integer defining the max allowable delta between two values (default=None; no limit)
- pyNastran.bdf.cards.collpase_card.build_thru_packs(packs: list[int], max_dv: int = 1, thru_split: int = 3.0) tuple[list[int], list[list[int]]][source]
Applies THRU and BY to packs to shorten output as Nastran does on cards like the SPOINT
- Parameters:
- packslist[pack]
- packlist[id_low, id_high, delta_id]
a list representation of the min/max/delta id values
- max_dvint; default=1
maximum allowed delta between two values
- thru_splitint; default=3
the length to not write THRU 3 : [10, 11, 12] will write as ‘10 THRU 12’ 4 : [10, 11, 12] will write as ‘10 11 12’
- Returns:
- singleslist[int]
the list of singles
- doubleslist[pack]
- packlist[varies]
[3, THRU, 13] [3, THRU, 13, BY, 5]
the double packs
- # invalid
- SET1,4000, 1, 3, THRU, 10, 20, THRU, 30
- # valid
- SET1,4000, 1
- SET1,4000, 3, THRU, 10
- SET1,4000, 20, THRU, 30
- returns
singles = [1] doubles = [[3, ‘THRU’, 10], [20, ‘THRU’, 30]]
- pyNastran.bdf.cards.collpase_card.collapse_colon_packs(fields: list[int], thru_split: int = 3) tuple[list[int], list[list[int]]][source]
Applies colons (:) to packs to represent THRU and BY as is used by Patran.
- Parameters:
- fieldslist[int]
the values to collapse
- thru_splitint; default=3
the length to not write THRU 3 : [10, 11, 12] will write as ‘10 THRU 12’ 4 : [10, 11, 12] will write as ‘10 11 12’
- Returns:
- singleslist[int]
the list of singles
- doubleslist[pack]
- packlist[varies]
[3, :, 13] [3, :, 13, :, 5]
the double packs
- # invalid
- SET1,4000, 1, 3, :, 10, 20, :, 30
- # valid
- SET1,4000, 1
- SET1,4000, 3, :, 10
- SET1,4000, 20, :, 30
- # output
- singles = [1]
- doubles = [[3, ‘:’, 10], [20, ‘:’, 30]]
