nested model blow up in 2D mode when activate WET_DRY

[Guotong_Deng]

Hi all,
I have run a 3-layer nested model in 2D mode successfully, but when I activated WET_DRY, the model blew up at about a grid-01 point in the contact area of grid 01 and grid 02.
I did not change other settings except activated WET_DRY. I tried many methods, such as smooth terrain and shoreline, but the results remained unchanged. When I changed the model from 2D mode to 3D mode, it did not blow up. So I think this is a problem in 2D mode but I don't know why.
Any comments are welcome.
Thanks!
