How to plot elemental custom results coming from a txt file in Mechanical?

Javier Vique

I am an standard user of Mechanical, with no DPF background. I have got an in-house tool which makes a evaluation of my structure giving elemental custom results which can be written into a txt/csv file. I want to plot these elemental custom results in Mechanical.

Python Result object allows users to plot elemental custom results in a very easily and intuitive way. The script given below just need a txt file called my_result.txt in the users_file folder of WB project.

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

    analysis = ExtAPI.DataModel.Project.Model.Analyses[0]
    user_files_dir = os.path.join(analysis.WorkingDir,'../../../user_files')
    ResultFile = os.path.join(user_files_dir, 'my_result.txt')
    
    elements = []
    result = []
    
    f = open(ResultFile, "r")
    Lines = f.readlines()
    for Line in Lines:
        Line = Line.split('\t')
        elements.append(float(Line[0]))
        result.append(float(Line[1].strip()))
    
    my_field = dpf.FieldsFactory.CreateScalarField(len(elements),'Elemental')
    [my_field.Add(id = elements[i], data = [result[i]]) for i in range(len(elements))]
    
    op = dpf.operators.utility.forward_fields_container()
    op.inputs.fields.Connect(my_field)

    dpf_workflow = dpf.Workflow()
    dpf_workflow.Add(op)
    # dpf_workflow.SetInputName(u, 0, 'time')
    # dpf_workflow.Connect('time', timeScop)
    dpf_workflow.SetOutputContour(op)
    dpf_workflow.Record('wf_id', False)
    this.WorkflowId = dpf_workflow.GetRecordedId()
