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).

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.
