It seems that you have to use MPP to run this model with *CONTACT_AUTOMATIC_SINGLE_SURFACE_TIED.

Also, you need to scope the slave faces to All Faces of the model or Both Faces on their interface. Otherwise it won't be bonded.

Finally, in WB LS-DYNA bonded contacts will be automatically created under Connections after geometry has been imported to Mechanical GUI and the distance between two faces is less than the specified tolerance. It may not be necessary to use Keyword Manager to define bonded contacts. Contact Properties can be inserted to modify the behavior of these bonded contacts such as type, penalty stiffness, etc.
