In general, there are several reasons for abnormal completion errors. However, the description mentions that one possible cause is the “Link is outside domain” issue, which can occur when there are problems in coupling nodes to mesh elements in the MIKE FLOOD coupling. The provided image shows a “mike 21/3 coupled model fm” that includes two SW and HD modules. Therefore, it is likely that there are multiple factors at play, possibly related to the created mesh file. However, to better understand the situation, it would be helpful to know if the abnormality occurred immediately after running the model or if it happened after a certain period of time.
