How to map results data into different geometries?

Here's an example which maps the results from an assembly to a specific part of the assembly. The result calculated is the max principal elastic strain. Following the script from the mapping data post, the updated script calculates the difference between the elastic strains of the part and the elastic strains of the assembly. Also a scale factor is added in lines 36-39.


Add a Python result object in Solution

Copy paste the following script and modify the path

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

def define_dpf_workflow(analysis):

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

    path_to_other_rst = os.path.join(r'C:\Users\Test','file.rst') # MODIFY THIS TO YOUR PATH
    analysis = ExtAPI.DataModel.Project.Model.Analyses[0]

    dataSource_1 = dpf.DataSources(analysis.ResultFileName)
    dataSource_2 = dpf.DataSources(path_to_other_rst)

    model_1 = dpf.Model(dataSource_1)
    mesh_1 = model_1.Mesh
    model_2 = dpf.Model(dataSource_2)
    mesh_2 = model_2.Mesh

    seqv_1 = dpf.operators.result.elastic_strain_principal_1()
    seqv_1.inputs.data_sources.Connect(dataSource_1)
    seqv_2 = dpf.operators.result.elastic_strain_principal_1()
    seqv_2.inputs.data_sources.Connect(dataSource_2)

    mapping_op = dpf.operators.mapping.on_coordinates()
    mapping_op.inputs.coordinates.Connect(mesh_1.CoordinatesField)
    mapping_op.inputs.fields_container.Connect(seqv_2.outputs.fields_container)
    mapping_op.inputs.mesh.Connect(mesh_1)

    minus_fc = dpf.operators.math.minus_fc()
    minus_fc.inputs.field_or_fields_container_A.Connect(seqv_1.outputs.fields_container)
    minus_fc.inputs.field_or_fields_container_B.Connect(mapping_op.outputs.fields_container.GetData())

    scale_field = dpf.operators.math.scale()
    scaleValue = 1
    scale_field.inputs.field.Connect(minus_fc)
    scale_field.inputs.ponderation.Connect(scaleValue)

    output = dpf.operators.utility.forward()
    output.inputs.any.Connect(scale_field)

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

Example model:
Solve the Assembly block (A), store the .rst file path, open the block with the Part (B), update the path in the Python Result object and solve the Part model.
