| Abstract: | An efficient, scalable, parallel algorithm for treating material surface contacts in solid mechanics finite element programs
has been implemented in a modular way for multiple-instruction, multiple-data (MIMD) parallel computers. The serial contact
detection algorithm that was developed previously for the transient dynamics finite element code PRONTO3D has been extended
for use in parallel computation by utilizing a dynamic (adaptive) load balancing algorithm. This approach is scalable to thousands
of computational nodes1 |
