Polyflow Moving Boundary – Method of Splines

  Hello,
  
  I have a problem simulating a moving boundary in Ansys Polyflow.
  
  This is my geometry and I have 2.5D axisymmetric geometry. When defining the 1st-local-remeshing [Method of Splines] it says that the bottom right domain is not sweepable:
  "In subtask fuid 2 the remeshing domain defined on SD4. is not sliceable. Select another method"
  
  Any ideas why that happens? does the connection to the upper-right domain be over the entire area? I dont get it
  
  Greetings,
  Philip
