Hello all,

I am trying to set up piston motion with a bowl in Fluent. The 2d geometry consists of three parts-piston bowl,piston motion,squish space. These three parts are created in UG, then assembled together. I imported the assemble file into Ansys Meshing Tool. However, There is a wall missing in fluent between piston bowl and piston motion after meshing. Fluent created a wall between squish space and piston motion automatically. Anyone knows how to let fluent create the wall for boundary condition purpose between piston bowl and piston motion? Any reply would be appreciated.
