Eulerian boundary region

Could you tell me how to define inflow and outflow eulerian boundary in ALE? MY ERROR IS "An Eulerian boundary region cannot overlap a sliding boundary region"

Defined in the first interface surface, and then modify the inp file, change to add

REGION TYPE = EULERIAN



*SURFACE, NAME=SURF1, REGION TYPE=SLIDING

TOP,S4



*SURFACE, NAME=EULER1, REGION TYPE=EULERIAN

EULER1,S3



Then, I go on the File/Import/Model...inp.file  - when he fined warning
