Hi everyone, I am trying to build a transient model to model lake-aquifer interaction using LAK3 package. At first, I’ve built a steady model without any problem. But when I change this model into the transient one, it can't run. I also checked my model. There is no error. If I inactivate the lake package, the transient model works correctly. I don’t know why this happens to my model? Does LAK3 package have a problem with transient modeling or special settings are needed? Thank you guys,
