  Hi, Need help
  
  what type of boundary condition i need to give while studying of the refrigerator door hinge. considering when a person applies a load at the end of the refrigerator door when it is open condition.

  Let's say that the Z axis is vertical for the sake of discussion. I would make two remote displacements.
  
  Pick the cylindrical face of the top hinge pin and set the X and Y displacement of the remote point to zero.
  
  Pick the cylindrical face of the bottom hinge pin and set the X, Y and Z displacement and the Z rotation to be zero.
  
  Those six constraints make the door fixed, now you can apply the force on the corner.

  For the top hinge all the rotation kept free?
  
  And bottom hinge X and Y kept free ?
  
  should i apply moment or only load is enough?
  
  please clarify

  Since the pin is very short, yes, leave all the X and Y rotations free.
  
  Just apply the down force on the end of the door, ANSYS will transfer the load through the parts to induce bending moments in the hinges.
