A post-processor may be scheduled to run immediately after the simulations, but before extracting the data.
Optimizing LS-DYNA input curves using analytical functions
Integrating Excel in LS-OPT
Multilevel Optimization in LS-OPT using nested optimization framework.
This example explains how to use an existing metamodel to evaluate further design points.
Import previously generated metamodels to perform metamodel-based tasks.
Imperfections for buckling and other instability problems can be created in LS-DYNA® using the *PERTURBATION keyword. These imperfections and perturbations are also known as stochastic fields. Modeling these imperfections is crucial for instability problems such a buckling analysis.
