XFEM - Galactic Extended FEM - Coming to a Screen Near You
Extended finite element method (XFEM) was developed by the late, great Dr. Ted Belytschko et al. at the end of the 90’s (see Wikipedia for more details). Since he worked closely with the developers of LS-DYNA on many other topics, it is natural to see his work implemented within ‘DYNA. I first met him in the early 90’s when I took his and Prof. Hughes week-long Nonlinear FEA Methods in Palo Alto, CA. As for myself, I sat in the back with a post-doctoral student from Budiansky’s group out of Harvard so he could explain to me what was going on since I was pretty much dazed and confused during the whole week.
