calculate()[source]#: Method used to do all the RF calculations and, optionally, export the results.

elements_manager_filter(mode: str = 'ADVANCED', table_print: str = 'NO')[source]#

Method used to find all the analysis elements (2D & 1D) of a N2PGetFasteners class and store them in three different categories: COMP_ELEMENTS, METAL_ELEMENTS & 1D_ELEMENTS.

Calling example #1:

>>> elements_manager_filter(mode = "SIMPLE", table_print = "EXCEL")

Calling example #2:

>>> elements_manager_filter(mode = "ADVANCED", table_print = "CSV")

The SIMPLE mode only creates the dictionary of analysis elements. This is intended to be used when the user first needs a dictionary containing all the analysis elements connected to the corresponding N2PJoint and N2PPlates objects.

The ADVANCED mode creates both the dictionary and each joint N2PJointAnalysisParameters class using the corresponding default values. This is intended to be used once the user has assigned a N2PFastenerSystem to each N2PJoint of the analysis. (Default).

table_print (OPTIONAL) = “NO” (DEFAULT) / “EXCEL” / “CSV”

Arg:: mode (str): “SIMPLE” or “ADVANCED” (Default) table_print (str): “EXCEL”, “CSV” or “NO (Default)

rf_and_lc_to_CSV() → None[source]#: Method used to export elements ALL RF for each LC to a CSV file

rf_min_and_lc_to_CSV() → None[source]#: Method used to export each element RF min and its corresponding LC to a CSV file

rf_min_and_lc_to_EXCEL() → None[source]#: Method used to export each element RF min and its corresponding LC to an EXCEL file
