There is an error with the SDR section_Long run with no result output

The software has been running for a long time without output. I hope you can help me to find out the middle problem.

More information is as follows:

Hi @VVyixiao -

Usually when SDR is running for a long time, it is because the DEM is very large in terms of resolution and/or overall size, so it takes a long time to create the hydrology layers derived from the DEM, such as flow accumulation. How large is your DEM?

Is that all of the log messages that are produced, or is there more? The messages there are only for a few seconds, but you say that it is running for a long time. In general, when posting to the forum, it’s helpful if you attach the entire log file (.txt) that the model produces in the Workspace, that way we have all of the messages produced.

Stacie is right about the DEM, but this also sounds very similar to a different issue with SDR on MacOS that is described over here:

If that sounds like your issue, see the last post in the thread for a workaround.
