The problem comeswhenthe mesh, the program gives mean error whenmeshing thelargesthoneycombpanel. Anyone have anyidea howtofix thisproblem?
Sounds like test is your best option. SWX sim does not have the right stuff for this class of problem. You need a damage model and robust NL dynamics likely an explicit code would be best. Say LS Dyna. This assumes that the bumbper is design to absorb energy as it is crushed which seems likely since honeycomb was choosen.
