How to export results on all bodies with DPF in Mechanical

Mike.Thompson

How can I export results data (i.e. temperature) for all bodies to their own files also with data like max and min at each time point?

See this example that contains a python code object. Run the solve and .csv files will be generated in the solution directory.

Code below:

import mech_dpf
import Ans.DataProcessing as dpf
from os.path import join
mech_dpf.setExtAPI(ExtAPI)

def after_solve(this, analysis):# Do not edit this line
#Get some basic data
DataSource=dpf.DataSources(analysis.ResultFileName)
DpfModel = dpf.Model(analysis.ResultFileName)
#Time scoping on all the result sets of the results file.
TimeScoping = dpf.TimeFreqScopingFactory.ScopingOnAllTimeFreqs(DpfModel)
TimeScoping.Ids=list(TimeScoping.Ids)[:-1]

#get all the temperature data
Temp_op=dpf.operators.result.temperature()
Temp_op.inputs.time_scoping.Connect(TimeScoping)
Temp_op.inputs.data_sources.Connect(DataSource)
Temp_FC=Temp_op.outputs.fields_container.GetData()

#Get the mesh nodal scoping of all the active bodies
Bodies = ExtAPI.DataModel.GetObjectsByType(DataModelObjectCategory.Body)
ActiveBodies = filter(lambda B: B.Suppressed==False, Bodies)

for B in ActiveBodies:
    #get the nodal mesh scoping per body
    SelInfo = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
    SelInfo.Ids=[B.GetGeoBody().Id]
    BodyMeshScoping=mech_dpf.GetNodeScopingByRefId(SelInfo)

    #Do a subset of the total temperature data
    op = dpf.operators.scoping.rescope_fc()
    op.inputs.fields_container.Connect(Temp_FC)
    op.inputs.mesh_scoping.Connect(BodyMeshScoping)
    op.inputs.default_value.Connect(0)
    Body_FC = op.outputs.fields_container.GetData()

    #Write this info to a .csv file
    CSV_op=dpf.operators.serialization.field_to_csv()
    CSV_op.inputs.field_or_fields_container.Connect(Body_FC)
    CSV_op.inputs.file_path.Connect(join(analysis.WorkingDir, B.Name+"_Temperatures.csv"))
    CSV_op.Run()

    #get the min and max.  result will be a min and max field with Time as Ids and a single value (min or max)
    MinMax_op= dpf.operators.min_max.min_max_fc()
    MinMax_op.inputs.fields_container.Connect(Body_FC)
    BodyMax_F=MinMax_op.outputs.field_max.GetData()
    BodyMin_F=MinMax_op.outputs.field_min.GetData()

    #Write this to .csv files as well.
    CSV_op=dpf.operators.serialization.field_to_csv()
    CSV_op.inputs.field_or_fields_container.Connect(BodyMax_F)
    CSV_op.inputs.file_path.Connect(join(analysis.WorkingDir, B.Name+"_Max.csv"))
    CSV_op.Run()

    CSV_op=dpf.operators.serialization.field_to_csv()
    CSV_op.inputs.field_or_fields_container.Connect(BodyMax_F)
    CSV_op.inputs.file_path.Connect(join(analysis.WorkingDir, B.Name+"_Min.csv"))
    CSV_op.Run()
