      Hello,

      I'm developing a FEM model to simulate the landing of a seaplane on water.

      I'm using the S-ALE method with a 2D beam model of the hull section. I need in output a plot with the pressure on different elements in time.

      I've used DATABASE_FSI but if I define multiple elements to plot, when I select in output the ASCII files i get a strange "bug": just half of the requested plot are created and the others are equal to zero. I get multiple plots with the same values but they should not be, the elements selected in pre processing are different and the results are wrong because the pressure are not real

      ASCII window

      Is possible to get the different plots in a single processing or I have to define one by one?
