converts a grid_type string to an integer

property dataframe: pd.DataFrame

alternate way to get the dataframe

get_data_code(prefix: str = '  ') → list[str]

get_unsteady_value()

print_data_members()

Prints out the “unique” vals of the case.

Uses a provided list of data_code[‘data_names’] to set the values for each subcase. Then populates a list of self.name+’s’ (by using setattr) with the current value. For example, if the variable name is ‘mode’, we make self.modes. Then to extract the values, we build a list of of the variables that were set like this and then loop over them to print their values.

This way there is no dependency on one result type having [‘mode’] and another result type having [‘mode’,’eigr’,’eigi’].

recast_gridtype_as_string(grid_type)

converts a grid_type integer to a string

Point type (per NX 10; OUG table; p.5-663): -1, Harmonic Point (my choice) -> ‘ ‘ = 538976288 (as an integer) =1, GRID Point =2, Scalar Point =3, Extra Point =4, Modal =5, p-elements, 0-DOF -6, p-elements, number of DOF
