  Dear all,
  
  I'm focusing a problem conceirning the export of transient results. I need the normal acceleration of the elements laying on a specific surface into a file.
  
  Does anyone know a best practice regardin that issue?

  Take a look at the *GET,ELEM command in the ANSYS Mechanical (M-APDL) command reference.
  
  Also here's a great answer from the web.

  Thanks for the help, the resource was already known to me. Still doesn't solve my problem. Let me get more specific:
  
  I perform a transient simulation and I would like to export the normal acceleration on each element (that is important because Ansys only calculates acceleration of nodes). of a given surface from all time steps. I need this information for a subsequent acoustic simulation.
  
  Now, I found already a way to fix the issue with the normal acceleration of an element. I used CFD Post to implement a point cloud on each mid surface nodes. But the problem is the enumeration of these nodes is kind of random. I can state the absolute coordinates of these nodes though but I would rather like to refer them to the original surface elements.
  
  I hope anyone has already encountered this problem and can try to explain a possible solution.
