I can extract the data from the field using the .data attribute but I am not able to find which is the attribute for listing the node IDs from the same field. However, when i print that field the node Ids are there.
Simplified code example:
model = dpf.Model(path)
my_ns = model.metadata.named_selection("FOO")
el_op = dpf.operators.result.elastic_strain(
time_scoping=[80],
mesh_scoping=my_ns,
data_sources=model,
bool_rotate_to_global=False,
requested_location="Nodal",
)
res_elastic = el_op.eval()
epel = res_elastic[0].data
