Getting information on elements in PyDPF

In PyDPF, how can I get: * the APDL element type (ie SOLID185, PLANE182, ...) * the APDL element type id (ie getting the "1" value in et,1,185)

the APDL element type (ie SOLID185, PLANE182, ...)
the APDL element type id (ie getting the "1" value in et,1,185)

For the APDL element type, use:

import ansys.dpf.core as dpf
model = dpf.Model(r"c:\temp\file.rst")
mesh = model.metadata.meshed_region
mesh.available_property_fields
field = mesh.property_field("apdl_element_type")

For the APDL element type id, use:

op = dpf.operators.metadata.property_field_provider_by_name()
op.inputs.streams_container.connect(model.metadata.streams_provider.outputs.streams_container)
op.inputs.property_name.connect("mapdl_element_type_id")
field = op.eval()
field.data

FYI... for a list of element type ids in the results file you can use this: (mech DPF implementation)

import mech_dpf
import Ans.DataProcessing as dpf
my_data_sources = dpf.DataSources(Model.Analyses[1].ResultFileName)
op = dpf.operators.metadata.property_field_provider_by_name() # operator instantiation
op.inputs.data_sources.Connect(my_data_sources)
op.inputs.property_name.Connect('mapdl_element_type_id')
my_property_field = op.outputs.property_field.GetData()
Ids = set(my_property_field.Data)
Ids
