I need to find the node with the max stress. How can I do this using DPF
Hello Jim, I think in the example: https://dpf.docs.pyansys.com/version/0.8/examples/00-basic/02-basic_field_containers.html#sphx-glr-examples-00-basic-02-basic-field-containers-py
the end there is are a few lines to show how to get max and Ids of the field.
Example how to do this in the mechanical scripting window with dpf. The example is von mises stress, but you can change that line to any result.
import mech_dpf import Ans.DataProcessing as dpf #Result Data analysis1 = ExtAPI.DataModel.Project.Model.Analyses[0] dataSource = dpf.DataSources(analysis1.Solution.ResultFilePath) #model my_model = dpf.Model(analysis1.Solution.ResultFilePath) #my mesh my_mesh = my_model.Mesh #time scoping my_time_scoping = 1 #Time list timelist = dpf.operators.metadata.time_freq_provider(data_sources=dataSource).outputs.gettime_freq_support().TimeFreqs.Data result_fc = dpf.operators.result.stress_von_mises(time_scoping=my_time_scoping,data_sources=dataSource).outputs.fields_container.GetData() result_field = result_fc[0] max_min_op = dpf.operators.min_max.min_max(field=result_field) max_id = max_min_op.outputs.field_max.GetData().ScopingIds max_value = max_min_op.outputs.field_max.GetData().Data min_id = max_min_op.outputs.field_min.GetData().ScopingIds min_value = max_min_op.outputs.field_min.GetData().Data max_result = [max_id[0],max_value[0]] min_result = [min_id[0],min_value[0]] print(max_result) print(min_result)
