Acoutic mass source


      Hi, I am having trouble inserting an acoustic mass source into the room. (I generated box) When I insert it the question mark appears. I just want to excite the room from the point (node) close to the corner of the room so that I can excite every mode of the room. How can I solve this problem? I am using the student license. Thank you in advance.

      Mass source can only be applied on a vertex,edge,face of an acoustic region (but not a node ).

      All the best
