In Mechanical, how to export animation file over a range of result sets instead of all result sets?

Mechanical doesn't have an option to choose a specific result set range to export animation and always exports the complete time history as an animation file. Eg: I have 10 result sets, but I want to export animation only for result set 1-3.

    One can use Python Result object in Mechanical to specify the result sets and then export the animation from this object.

    Step 1: In Mechanical, add a Python Result object. This should by default plot Total Deformation at last result set.

    Step 2: Modify the Python Result object according to the result you need (Modify - Operators etc). In this example, for simplicity, I am omitting this step.

    Step 3: Paste the below script in your python result object.

    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
    mech_dpf.setExtAPI(ExtAPI)
    dataSource = dpf.DataSources(analysis.ResultFileName)
    u = dpf.operators.result.displacement()
    nrm = dpf.operators.math.norm_fc()
    timeScop = dpf.Scoping()
    #Specify the result sets that are needed to be extracted
    timeScop.Ids = [1,2,3]
    u.inputs.time_scoping.Connect(timeScop)
    u.inputs.data_sources.Connect(dataSource)
    nrm.Connect(u)
    dpf_workflow = dpf.Workflow()
    dpf_workflow.Add(u)
    dpf_workflow.Add(nrm)
    dpf_workflow.SetInputName(u, 0, 'time')
    dpf_workflow.Connect('time', timeScop)
    dpf_workflow.SetOutputContour(nrm)
    dpf_workflow.SetOutputWarpField(u)
    dpf_workflow.Record('wf_id', False)
    this.WorkflowId = dpf_workflow.GetRecordedId()

    Step 4: RMB on Python Result object --> Connect. Evaluate All Results and animate the results as usual for this Python result object and export the animation.
