Find the maximum value in a field AND corresponding scoping ID

Jim Kosloski

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)
