nIt should work in Explicit Dynamics also. The mesh is required to be Linear elements for that so you must have at least 4 elements through the thickness. The problem now is that the solution time goes up as the minimum element edge length goes down. Use the Mesh Metric Characteristic Length to find the element with the minimum value and try to improve the mesh to make that value as large as possible. Changing the legs to shell elements instead of solid elements will help.nSince Explicit Dynamics takes longer to solve, you don't need to simulate all the time after the landing gear reaches the maximum displacement downward, which is around the time F/4. So make the end time a bit longer than F/4 but that will be much less than F/2.n
