Accessing SVAR (User State Variable) from UPF in DPF

flyingwhiteduck · April 7

Hi, all community members!

I've been writing some concrete models using ANSYS UPF functions for some time now and am in need of some result post-processing, so I've been figuring out the DPF functionality for some time now.

The question is: I'm not entirely sure how to access User State Variables in Python Result objects. I'm trying to plot one but with no luck so far.

I'm using ANSYS Mechanical 2022R1. State Variables are initialised from Mechanical by APDL script object using the "TB,STATE,matid,,20" string. In default results, they are accessed using SVAR() User Defined Result.

So far I found a result operator named "state variable" (which seem to be what i need), but I was not able to plot it successfully. Below Python Results content is presented.

    import mech_dpf
    import Ans.DataProcessing as dpf
    mech_dpf.setExtAPI(ExtAPI)
    data_source = dpf.DataSources(analysis.ResultFileName)
    
    upf_result_op = dpf.operators.result.state_variable()
    upf_result_op.inputs.data_sources.Connect(data_source)
    upf_result_op.inputs.item_index(3)
    
    dpf_workflow = dpf.Workflow()
    dpf_workflow.Add(upf_result_op)
    dpf_workflow.SetOutputContour(upf_result_op)
    dpf_workflow.Record('wf_id', False)
    this.WorkflowId = dpf_workflow.GetRecordedId()
