Performance Of Interface Elements In The Finite Element Method
… implemented in the finite element codes such as MSC.NASTRAN, which is used in this study. Interface elements in MSC.NASTRAN provide a tool to transition between a shell-meshed region to another shell-meshed region as well as from a shell-meshed region to a solid-meshed region. Often, in practice …

Vibration Analysis of a Fan/Compressor Blade
… commercially available finite element solver, MSC.NASTRAN, and correlated with the analytical solutions. The finite element analysis was performed in three different models, straight plate, tapered solid, and blade models. Finally, the recommendations are made for more accurate finite element …

Identification and investigation of local optima in aerospace structural design
… internal structure of a simplified wing spoiler. MSC.NASTRAN was used to optimize each discretized location of an additional rib with the aid of a Patran Command Language (PCL) algorithm. The objective function of minimum weight was approximated as a multimodal function in a 2D smooth curve where …

Structural Modeling and Optimization of Aircraft Wings having Curvilinear Spars and Ribs (SpaRibs)
… wing is modeled using commercial FEA software, MSC.PATRAN and analyzed using MSC.NASTRAN which are from within EBF3GLWingOpt. Using this code a significant weight reduction for a transport aircraft wing has been achieved.

EBF3GLWingOpt: A Framework for Multidisciplinary Design Optimization of Wings Using SpaRibs
… to integrate several commercial software: MSC.PATRAN for pre and post processing, MSC.NASTRAN for finite element analysis. An approximate optimization method is developed for the stiffened panel optimization so as to reduce the computational cost. The integrated global-local optimization …
