Failsafe topology optimization:
\nFSO divides the structure into damage zones and generates multiple models (equal to the number of failure zones). Each model is the same as the original model minus one failure zone. In this process, the FSO method is applied by running Topology Optimization simultaneously for all such generated models and a final design is an output that is optimized to account for all generated models. If the number of damage zones is large, the number of SPMD domains is high. Such a job typically requires to be run on multiple nodes with the cluster setup.<\/p>\n","protected":false},"excerpt":{"rendered":"
