  Hi all,
  I just wanna know whether it is possible or if there is a command to constraint a displacement in only one direction, that means if I know that my assembly or piece cannot move in +Y direction but let -Y direction as free.
  
  Kind regards

  Hi, if you have face bottom to it or under the applied displacement or force set the displacment in the face to 0 and load the top face in y direction, this should do the job.
  Cheers, Ram

  Are you using Mechanical? You can try compression-only support for this. Or you may want to use compression only (or tension only) spring with large stiffness, which is a beta feature in Mechanical.

  Hi,
  
  You can model an object in contact (frictionless contact) with the part of interest such that the object in contact does not allow the other part to move in positive Y and allows it to move in negative Y-direction.
