Subcase creation/extraction class
- class pyNastran.bdf.subcase.Subcase(id=0)[source]
Bases:
objectSubcase creation/extraction class
- add_integer_type(key: str, value: int) None[source]
- Simple way to add something of the form:
SPC = 1
subcase.add_integer_type(‘SPC’, 1) vs. subcase.add(‘SPC’, 1, [], ‘STRESS-type’)
- add_result_type(key: str, value: int | str, options: list[str]) None[source]
- Simple way to add something of the form:
DISP(PLOT) = ALL STRESS(PLOT) = ALL FORCE(PLOT) = 1
subcase.add_integer_type(‘SPC’, 1, [‘PLOT’]) vs. subcase.add(‘SPC’, ‘ALL’, [‘PLOT’], ‘STRESS-type’)
- allowed_param_types = ['SET-type', 'CSV-type', 'SUBCASE-type', 'KEY-type', 'STRESS-type', 'STRING-type', 'OBJ-type']
- finish_subcase() None[source]
Removes the subcase parameter from the subcase to avoid printing it in a funny spot
- get_int_parameter(param_name: str, msg: str = '', obj: bool = False) tuple[int, list[Any]][source]
Gets the [value, options] for a subcase.
- Parameters:
- param_namestr
the case control parameters to get
- objbool; default=False
should the object be returned
- Returns:
- valueint
the value of the parameter 1 in LOAD = 1
- optionslist[varies]
the values in parentheses [‘PLOT’, ‘PRINT’] in STRESS(PLOT,PRINT) = ALL???
- get_parameter(param_name: str, msg: str = '', obj: bool = False) tuple[int | str, list[Any]][source]
Gets the [value, options] for a subcase.
- Parameters:
- param_namestr
the case control parameters to get
- objbool; default=False
should the object be returned
- Returns:
- valuevaries
the value of the parameter ‘ALL’ in STRESS(PLOT,PRINT) = ALL
- optionslist[varies]
the values in parentheses [‘PLOT’, ‘PRINT’] in STRESS(PLOT,PRINT) = ALL
- get_str_parameter(param_name: str, msg: str = '', obj: bool = False) tuple[str, list[Any]][source]
Gets the [value, options] for a subcase.
- Parameters:
- param_namestr
the case control parameters to get
- objbool; default=False
should the object be returned
- Returns:
- valuestr
the value of the parameter ‘ALL’ in STRESS(PLOT,PRINT) = ALL
- optionslist[varies]
the values in parentheses [‘PLOT’, ‘PRINT’] in STRESS(PLOT,PRINT) = ALL
- has_parameter(*param_names: list[str]) list[bool][source]
Checks to see if one or more parameter names are in the subcase.
- Parameters:
- param_namesstr; list[str]
the case control parameters to check for
- Returns:
- existslist[bool]
do the parameters exist
- print_param(key: str, param: tuple[Any, Any, str]) str[source]
Prints a single entry of the a subcase from the global or local subcase list.
- solCodeMap = {1: 101, 21: 101, 24: 101, 26: 101, 61: 101, 64: 106, 66: 106, 68: 106, 76: 101, 99: 129, 144: 101, 187: 101}
- subcase_sorted(lst: list[str]) list[str][source]
Does a “smart” sort on the keys such that SET cards increment in numerical order. Also puts the sets first.
- Parameters:
- lstlist[str]
the list of subcase list objects (list_a)
- Returns:
- list_blist[str]
the sorted version of list_a
- pyNastran.bdf.subcase.get_analysis_code(sol: int) int[source]
Maps the solution number to the OP2 analysis code.
8 - post-buckling (maybe 7 depending on NLPARM???)
- # not important
3/4 - differential stiffness (obsolete)
11 - old geometric nonlinear statics
12 - contran (???)

- pyNastran.bdf.subcase.get_device_code(options: Any, unused_value: Any) int[source]
Gets the device code of a given set of options and value
- Parameters:
- optionslist[int/float/str]
the options for a parameter
- unused_valueint/float/str
the value of the parameter
- Returns:
- device_codeint
The OP2 device code
0 - No output 1 - PRINT 2 - PLOT 3 - PRINT, PLOT 4 - PUNCH 5 - PRINT, PUNCH 6 - PRINT, PLOT, PUNCH
- pyNastran.bdf.subcase.get_format_code(options: list[str], unused_value: Any) int[source]
Gets the format code that will be used by the op2 based on the options.
- Parameters:
- optionslist[int/float/str]
the options for a parameter
- unused_valueint/float/str
the value of the parameter
- .. todo:: not done…only supports REAL, IMAG, PHASE, not RANDOM
- pyNastran.bdf.subcase.get_sort_code(options: list[str], unused_value) int[source]
Gets the sort code of a given set of options and value
- Parameters:
- optionslist[int/str]
the options for a parameter
- unused_valueint; str
the value of the parameter
- pyNastran.bdf.subcase.get_stress_code(key: str, options: dict[str, Any], unused_value: Any) int[source]
Method get_stress_code:
Note
the individual element must take the stress_code and reduce
it to what the element can return. For example, for an isotropic CQUAD4 the fiber field doesnt mean anything.
BAR - no von mises/fiber ISOTROPIC - no fiber
Todo
how does the MATERIAL bit get turned on? I’m assuming it’s element dependent…
- pyNastran.bdf.subcase.get_table_code(sol: int, table_name: str, unused_options) int[source]
Gets the table code of a given parameter. For example, the DISPLACMENT(PLOT,POST)=ALL makes an OUGV1 table and stores the displacement. This has an OP2 table code of 1, unless you’re running a modal solution, in which case it makes an OUGV1 table of eigenvectors and has a table code of 7.
- Parameters:
- optionslist[int/float/str]
the options for a parameter
- valueint/float/str
the value of the parameter
- Returns:
- table_codeint
the OP2 table_code
