Read Imported Load h5 created by DPF

Ayush Kumar

DPF creates an h5 file when I add an Imported Temperature condition in Mechanical. How do I read the data out of that file?

Ayush Kumar

The file is named "LoadMapping<Object_ID>_Data.h5"

The result is written as "target_data_<Object_ID>" in the h5 file, we need to use the custom read operator:

import re
import os
from ansys.dpf import core as dpf
dpf.start_local_server(ansys_path=r"C:\Program Files\ANSYS Inc\v252")

nid = 481
file_name = "LoadMapping70_Data.h5"
h5 = os.path.join(r"…", file_name)

ds = dpf.DataSources()
ds.set_result_file_path(h5, "h5dpf")

ts = dpf.Scoping()
ts.ids = [1, 2]  # Input time-steps

object_id = int(re.search(r'\d+', file_name).group())
result_name = f"target_data_{object_id}"

# Read Custom Result
custom_res = dpf.Operator("hdf5::h5dpf::custom")
custom_res.inputs.data_sources.connect(ds)
custom_res.inputs.result_name.connect(result_name)
custom_res.inputs.time_scoping.connect(ts)
my_field_or_fields_container = custom_res.outputs.field_or_fields_container_as_fields_container()
print(my_field_or_fields_container)

for i in ts.ids:
    temp = my_field_or_fields_container.get_field_by_time_id(i).get_entity_data_by_id(nid)
    print(temp)
