Structured ALE analysis with MPP dbfsi issue

      Hello, I've created a model to calculate the pressure on a hull during a water entry.

      I've used S-ALE method and on my PC it works, I get pressure measures using DATABASE_FSI keyword and then exporting the csv files.

      I have to get a bigger analysis of a complete structure impacting water and I use a MPP.

      I've just tryed to run the same analysis (the one which works on my pc) on the MPP but I can't get the dbfsi file I need.

      The plot I get in post processing are just many plots all with the same values which are not correct, they are all equal to the results of the first sensor I've placed on the bottom of the shell element. The dbfsi doesn't appear in the ASCII files and so I have to select the BINOUT option and import the "results".

      I don't understand what I'm doing wrong, the run files are the same but the results I need don't appear

       

      Correct results
