Good day everyone.<\/p>\n

<\/p>\n<\/p>\n

I would like to ask for some knowledge share for analyzing a structure in Explicit with beam mesh.<\/p>\n

Currently i am trying to observe a reaction of a structure before adding any accessories to hold an impact absorbing of a tubular structure. As Mr @peteroznewman<\/a> kindly explain before, i could not run without the whole system as all the equipment will be in series and without one of the other, the reaction force will be higher. Thus i am trying for a few months, and keep failing with the solid mesh, as the elements is too high and the simulation time is too long. Thus i am switching for a beam mesh for the tubular structure as it decreases the elements by a lot.<\/p>\n

So what am i doing is that i model a small cube with modified density to get the energy required, as i am only observing the elements which get impacted, which having the original density.<\/p>\n

However, for the problem assessment, how do i make sure that cube to hit the beam elements as i could not create any contact from the surface contact to the line elements of the beam. I tried to run the simulations as it, and it seems the model almost went through the beam mesh. <\/p>\n
