I was trying to perform a drop test of a
flexible (elastic) solid sphere on a rigid flat target with ANSYS LS
dyna. Do you know what is the best element and the corresponding
options of that elemet, how to mesh the ball to get best results,
which is better ANSYS or ANSYS LS Dyna for this problem? iam a student and have been
trying to solve this problem, but my results sometimes are very far from
the anlytical solution of HERTZ dynamic equation. Please guide me. Also when I refine the meshes
more, my computer ask for more memory using -m command which i do not
understand. Please help me!!!!!
