Dear Professor, ,I am a novice. I want to do a simulation,about explicit dynamic,a brick drop to water.The water is eulerian (reference frame) ,and the brick is lagrangian(reference frame),they have a contect region of frictionless , when I click the "solve" button , the error display ,and  shows:"The Contact and Target scoping for a Contact Region cannot be scoped to a body with reference frame set to Eulerian."

Contacts and Body Interactions are only used between the bodies that are in the Lagrange Reference Frame. They are not supposed to be used on the bodies between the Lagrange Reference Frame and Eulerian (Virtual) Frame. So you need to suppress these contacts.
The interaction between the bodies in Lagrange and Eulerian Reference Frames are automatic. It doesn't need additional setup. The only requirement is that the bodies with Lagrange reference frame have to be inside the Eulerian domain (the bodies with Eulerian frame).
