      I’m not trying to exactly replicate the geometry shown in the video, but I would like to apply a dynamic mesh to a cylinder geometry to visualize the piston motion (around 80–90 mm stroke) using a UDF rather than the built-in in-cylinder model in ANSYS.
      How can I stretch or deform a sweep mesh like in the video?
