S-ALE method FSI hull impact, pressure sensors issue

      Hello, I've used the S-ALE method to simulate a hull impact on the water.

      I've definied the hull with SECTION_SHELL and the water/air with ALE_STRUCTURED_FSI.

      The analysis works but I can't get the "correct" pressure on the shell. I've tryed with different approaches (DATABASE_FSI, DATABASE_FSI_SENSOR...) but I can't get the results: with the sensors there's a problem about the offset position and with database_fsi I get just the average pressure on the shell but I need the one on just a few shell elements.

      Is there any keyword or method to measure the local pressure on a few shell elements?
