  I can't always choose the side exposed in that direction
  how to select that part?
  
  Thanks!

  It looks like you have a 2D model. In SpaceClaim, create two radial lines on the circle at angles that intersects the circle at the two points where you want to break the edge to apply a pressure load to that segment.

    thank you！ but if i apply pressure on a specific segment , i still cannot choose the segment exposed in that direction after starting to solve this model

  You can define a Fluid Pressure Penetration through Contact elements.
