Fields
attribute data_dict: Dict[str, tidy3d.components.data.MonitorData] [Required]#

Mapping of name to each MonitorData in the collection.

add_to_group(hdf5_grp) → None#

Add data from a AbstractFieldData to an hdf5 group .

ensure_member_exists(member_name: str)#

make sure a member of collection is present in data

classmethod load_from_group(hdf5_grp)#

Load a AbstractFieldData from hdf5 group containing data.

property data: Dict[str, xarray.core.dataarray.DataArray]#

For field quantities, store a single xarray DataArray for each field. These all go in a single xarray Dataset, which keeps track of the shared coords.

Returns

Mapping of data dict keys to corresponding DataArray from .data property. For more details refer to xarray’s Documentaton.

Return type

Dict[str, xarray.DataArray]

property sim_data_getitem: tidy3d.components.data.Tidy3dData#

What gets returned by sim_data[‘monitor_data_name’]
