    You need to know the MPC184 Element ID, that can be found using the User Defined Result in Mechanical "PNUMELEM" and then use the following code.

    from ansys.dpf import core as dpf
    
    rst_path = r"\Path\to\file.rst"
    model = dpf.Model(rst_path)
    
    ms = dpf.Scoping()
    """ MPC 184 Element ID eg. 3774 """
    ms.ids = [3771] jfx = model.operator("mapdl::smisc")
    jfx.inputs.mesh_scoping.connect(ms)
    """ Use the following indexes in the next line.
    1: Fx, 2: Fy, 3: Fz """ jfx.inputs.item_index.connect(1)
    fx = jfx.outputs.fields_container.get_data()[0].data
