Hello. I am trying to model the estuary of the Negro River. I've been trying for a long time to find a suitable model, but I can't get the model to run correctly.The domain is as follows (due to the availability of metering stations). I have the following options:1- Model with a single grid for the entire domain including the section of the Negro River (blue box in image 1).2- Model a parent model and then include a submodel with a curvilinear grid for the river (image 2).According to what you can see, what can you advise me?I was trying to run the model with the option mentioned in point 1, and this throws the error that I show in image 3.Is there any possibility of being able to do these queries in a personalized way? Thanks.
