classmethod add_card(card, comment='')

Adds a CGEN card from BDF.add_card(...)

Parameters:

cardBDFCard()

a BDFCard object

commentstr; default=’’

a comment for the card

cross_reference(model: BDF) → None

property node_ids

raw_fields()

Gets the fields in their unmodified form

Returns:

fieldslist[int/float/str]

the fields that define the card

repr_fields()

Gets the fields in their simplified form

Returns:

fieldslist[int/float/str]

the fields that define the card

safe_cross_reference(model)

type = 'CGEN'

uncross_reference(model)

validate()

card checking method that should be overwritten

write_card(size: int = 8, is_double: bool = False) → str

Writes the card with the specified width and precision

Parameters:

sizeint (default=8)

size of the field; {8, 16}

is_doublebool (default=False)

is this card double precision

Returns:

msgstr

the string representation of the card

class pyNastran.bdf.cards.msgmesh.GMCORD(cid, entity, gm_ids, comment='')

Bases: BaseCard

defines the GMCOORD class

GMCORD | CID | ENTITY | ID1 | ID2 | GMCORD | 101 | GMCURV | 26 | 44 |

Creates a GMCOORD

classmethod _init_from_empty()

classmethod add_card(card, comment='')

Adds a GMCORD card from BDF.add_card(...)

Parameters:

cardBDFCard()

a BDFCard object

commentstr; default=’’

a comment for the card

static cross_reference(model: BDF) → None

raw_fields()

setup()

type = 'GMCORD'

static uncross_reference() → None

Removes cross-reference links

write_card(size: int = 8, is_double: bool = False) → str

Writes the card with the specified width and precision

Parameters:

sizeint (default=8)

size of the field; {8, 16}

is_doublebool (default=False)

classmethod add_card(card, comment='')

Adds a GMLOAD card from BDF.add_card(...)

Parameters:

cardBDFCard()

a BDFCard object

commentstr; default=’’

uncross_reference() → None

Removes cross-reference links

write_card(size: int = 8, is_double: bool = False) → str

The writer method used by BDF.write_card()

Parameters:

sizeint; default=8

the size of the card (8/16)
