Modeling of point masses
I'm trying to do an impact simulation between a missile and a plate target. The missile radome is made from composite material and is modeled as shell elements. The missile body sections are made from aluminium alloy and are modeled as shell elements with attached point masses (see picture below). The structure is very large, so the simulation is very slow. I want to reduce the model. Which part of the missile I'm interested in is the radome part, so I want to reduce the missile body as single line of point masses . But I don't know how to do that, and how to link the point masses together. Could any one tell me how to overcome this situation?
