  • Block moved after performing a UNION in the &SURFACE Menu?

    Q: Why does MOSES "move my block" a small bit when I perform a UNION in the &SURFACE Menu? REV 5.08 A: Yes, &SURFACE will "move your blocks around" if it has to eliminate undesirable intersections. In particular, the algorithm here relies on the fact…

  • Hull model composed of various pieces

    Q: Can I use a hull model composed of various PGEN definitions that share surfaces for hydrodynamics? REV 5.10 A: Absolutely not! You must have a single enclosed surface for hydrodynamics computations. You should use COMPART_SUM panels to make sure…

  • Hydrodynamic and Hydrostatic calculations

    Q: I have a piece that I want to be included for hydrodynamic calculations but I do not want it included for hydrostatic calculations. What options do I used in the definition? REV 7.04 A: You need to give the part just a little bit of displacement…
