Dyna hourglass
WebMay 21, 2024 · Preferred hourglass formulations for foams are type 6 with hourglass coef = 0.1 if low velocity impact, and type 2 or 3 with hourglass coef. = 0.1 if high velocity impact. WebLS-DYNA has various algorithms for inhibiting hourglass modes. The default algorithm (type 1), while the cheapest, is generally not the most effective algorithm. A way to …
