      please use a value close to initial mesh for 'cell height'. 

      you must be knowing your initial mesh size. 

      if not got to viewing - mouse - probe - long description. then select any position by right mouse button. you will get coordinates. from there you can determine mesh size. 

      if this helps you please mark this as 'is solution' to help others on forum.

      Thank you. Sorry, I ask you another question: after 'preview mesh motion' the mesh remains in the last position, how do i reset it to the initial position?

      you have to save case file before using preview mesh motion. you can not go to initial position after using preview mesh motion. you will need to read previous file.
