How can I create a temperature contour plot from an existing .rth file?

I do have results of a transient thermal analysis performed in Ansys Mechanical. In a next step I would like to use PyDPF to create a contour plot of the temperature of my body and save the contour plot as a picture.

    Hello, you should be able to use a python result to plot the temperature and export the image with something similar to this example below:

    def post_started(sender, analysis):# Do not edit this line
    define_dpf_workflow(analysis)

# Uncomment this function to enable retrieving results from the table/chart
# def table_retrieve_result(value):# Do not edit this line
    # import mech_dpf
    # import Ans.DataProcessing as dpf
    # wf = dpf.Workflow(this.WorkflowId)
    # wf.Connect('contour_selector', value)
    # this.Evaluate()

def define_dpf_workflow(analysis):
    import mech_dpf
    import Ans.DataProcessing as dpf
    import os
    mech_dpf.setExtAPI(ExtAPI)

    analysis = ExtAPI.DataModel.Project.Model.Analyses[0]

    #Results files paths
    resultFile1 = analysis.ResultFileName

    #Data Sources
    dataSource1 = dpf.DataSources(resultFile1)

    #Time Sets in Results File
    timeScopOp1 = dpf.operators.metadata.time_freq_provider()
    timeScopOp1.inputs.data_sources.Connect(dataSource1)
    timeFreq1 = timeScopOp1.outputs.time_freq_support.GetData()
    timeResultsSets1 = timeFreq1.NumberSets

    #Time Scoping
    timeScopingOp1 = dpf.Scoping()
    timeScopingOp1.Ids = [10]
    timeScopingOp1.Location = "Time"

    #Temperature Results
    tempOp1 = dpf.operators.result.temperature()
    tempOp1.inputs.data_sources.Connect(dataSource1)
    tempOp1.inputs.time_scoping.Connect(timeScopingOp1)
    temp1 = tempOp1.outputs.fields_container.GetData()

    dpf_workflow = dpf.Workflow()
    dpf_workflow.Add(tempOp1)
    dpf_workflow.SetOutputContour(tempOp1)
    dpf_workflow.Record('wf_id', False)
    this.WorkflowId = dpf_workflow.GetRecordedId()

    imagePath = analysis.WorkingDir
    imageName = "imag1.png"
    totalDir = os.path.join(imagePath,imageName)
    ExtAPI.Graphics.ExportImage(totalDir)

    You should get something like this:
