Description of the bug

The DCIR result (shows "Neither" in V1 Node to Ground) is not consistent with the simulation setting("Negative").

setup.add_source_terminal_to_ground("V1", 1) does not work.

Steps To Reproduce

Run the code below, open ANSYS-HSD_V1.siw and view the DCIR setup and result

import os
import pyedb
from pyedb.misc.downloads import download_file

temp_dir = "c:/demo"
targetfile = download_file("edb/ANSYS-HSD_V1.aedb", destination=temp_dir)
aedt_file = targetfile[:-4] + "aedt"

if os.path.exists(aedt_file):
    os.remove(aedt_file)

edb_version = "2024.1"
edb = pyedb.Edb(edbpath=targetfile, edbversion=edb_version)

edb.siwave.create_voltage_source_on_net("U1", "AVCC_1V3", "U1", "GND", 1.3, 0, "V1")
edb.siwave.create_current_source_on_net("IC2", "NetD3_2", "IC2", "GND", 1.0, 0, "I1")
setup = edb.siwave.add_siwave_dc_analysis("myDCIR_4")
setup.use_dc_custom_settings = True
setup.set_dc_slider = 0
setup.add_source_terminal_to_ground("V1", 1)

edb.save_edb()
siw_file = edb.solve_siwave()
edb.export_siwave_dc_results(siw_file, setup.name)

edb.close_edb()
