A problem about the connection of two grids

Hi EFDC Users,How to connect two grids like what is shown in the first picture.The two grids(the red one and the green one) have more than one joints to connect,if I connect one joint,there will be something terrible happens(as is shown in the second picture). I am worried to know how to solve the problem.SincerelySsr

You might consider using cell connections in EFDC_Explorer instead. This would allow you to connect these grids together without having the problem you are seeing.Take a look at the following page: https://eemodelingsystem.atlassian.net/wiki/spaces/EEREF/pages/2379971/Fixed+Parameters

Thank you very much for your help.
