      How should I set LS-Prepost to achieve the pressure cloud map style shown in the figure

      In the calculation case, I used the S-ALE algorithm

      Hello User,

      • First, pick what you are contouring with Post → Fringe Component (Fringe → Fcomp), e.g. von Mises stress, displacement, etc.

      • Then turn on the fringe display if needed (Fringe on/off button in the main toolbar or via the Fringe menu).

      • Use Post → Fringe Range (FriRang) to control:

        • Min/max values (Global, Current).

        • Number of levels, averaging option, or to identify min/max entities.

      Let me know if this doesn't help.

      Regards,

      Nanda.

        Hello Nanda,I followed your method and the post line contour mode can be displayed normally in the calculation case using the ALE method. But in the calculation case using the S-ALE method, I selected a part and selected pressure in the "Fringe Component", but when I clicked on "post line contour mode" in the "Fringe on/off button", the part I selected disappeared from the screen. How should I set the post line contour mode correctly in the calculation case using the S-ALE method?

      Hello,

      • If the part disappears when switching to line contour mode, try toggling between element shade modes (View > Element Shade > Mesh) or switching between flat and smooth shading in the View menu. This can help restore visibility for S-ALE meshes.
      • Ensure that the correct result state (time) is selected in the Animate window, as S-ALE simulations may have moving meshes, and the display can change between time steps. 
      • If issues persist, try resetting the display using the Clear button to remove previous selections, then reapply the desired contour and shading settings.
