Blow up may caused by contact file

[Guotong_Deng]

Hi all,

I am running a two-layer nested model, but it blew up after running a few steps. I run the two models separately and there is no problem.

During the nested operation, the TotVolume of the first layer became extremely large, and the Maximum barotropic Courant Number of the two layers also appeared abnormal, but these are normal when running these two grid separately, so I suspect that it is the problem of contact file.
