You can use the following code in Mechanical Scripting console, please change the node_id and GetDataSources index accordingly.

NOTE - Works only from 2022R1 onwards

import mech_dpf
import Ans.DataProcessing as dpf

mech_dpf.setExtAPI(ExtAPI)
model = dpf.Model(mech_dpf.GetDataSources(1))

node_id = 1300

mesh = model.Mesh
field_nodal = mesh.NodalConnectivityPropertyField
element_indices = field_nodal.GetEntityDataById(node_id)

element_scope = mesh.ElementScoping
all_elements = [element_scope.IdByIndex(index) for index in element_indices]

e_prop = mesh.GetPropertyField("apdl_element_type")
e_types = [e_prop.GetEntityDataById(index)[0] for index in all_elements]

mat_prop = mesh.GetPropertyField("mat")
mat_ids = [mat_prop.GetEntityDataById(index)[0] for index in all_elements]

print e_types
print mat_ids

Hello Ayush,

"apdl_element_type" and "mat" are two property names. How do I find all available property names?

Thanks
