OpenDSS 13Bus example fails to compile on Linux (IEEELineCodes.DSS vs .dss) #129
Description
The bundled OpenDSS/13Bus/IEEE13Nodeckt.dss redirects to IEEELineCodes.dss (line 46), but the file in the folder is named IEEELineCodes.DSS. On a case-sensitive filesystem the redirect fails and the circuit loads with no buses.
Steps (powermcp 0.4.0, Linux):
compile_opendss_fileon13Bus/IEEE13Nodeckt.dssreturns success.solve_snapshotreturnsconverged: false, andget_results_summary_recordsshows all zeros (0 buses, 9 elements).- Running the same file through py-dss-interface directly prints
Redirect File: ".../IEEELineCodes.dss" Not Found.
Renaming IEEELineCodes.DSS to IEEELineCodes.dss fixes it: the feeder converges in 3 control iterations with min/max voltages of 0.961 and 1.056 pu.
Two small improvements would help: rename the file in the repo, and have compile_opendss_file report failed redirects instead of returning success: true.

Thanks for the report. The casing part is fixed in #136 (merged): both 13-bus masters now
redirect IEEELineCodes.DSS, matching the file. A new test checks every redirect/compile/BusCoords target in the shipped.dssfiles by exact name, so a mismatch like this fails CI on any platform.The second suggestion is still open:
compile_opendss_fileshould report a failedRedirectinstead of returningsuccess: true. @PauloRadatz @samtalki, could you help with this one? We can't run OpenDSS on Linux here, and I'd rather not guess at the engine's error channel.dss_tools.configuration.compile_dss(...), where does a failedRedirectshow up reliably? Is it in the stringdss.text("Compile [...]")returns (theRedirect File: ... Not Found.message), or in an error code/description onpy_dss_interface? Or is it better to check a property after compiling, such as the bus or element count?circuit_readiness()already capture this, or could it?py_dss_toolkitversion addedconfiguration.circuit_readiness()? On an arm64 Mac, uv resolves theopendssextra (py_dss_toolkit, unpinned) to 0.7.0, which doesn't have it. The extra probably needs a version floor.
