How to monitor temperature on an overset surface during mesh motion?

      Dear all,

      with this post I would like to ask how to keep point on moving surface during dynamic mesh simulation (Fig. 1) in order to track certain dependent variable in time?

      You can't easily do this as the "point" can't move with the domain. The best approach is to split a cell/facet off the surface in Fluent (use an adaption register and the Separate tool in Domain tab. You then monitor what you want on that facet (it'll show as a separate surface).

      Dear Mr. Rob thank you very much for your response.
      I did it the following way:
      two cells adjacent to the central point of the object were stored in a separate register (Fig. 1);
      Fig. 1 The cells adjacent to the specimen center were selected in a specific region.
      according to your instruction, these cells were separated;
      the dependent variable may now be tracked using "Report Files" or "Report Plots" options as a Volume average, not anymore in "Calculation Activities" and being exported as cell centered ASCII file at specific location.
