Optimus Interfaces

NASTRAN

The direct interface for Nastran supports the efficient optimization of engineering challenges involving multidisciplinary FEA simulation. It automates the creation of an engineering workflow that contains Nastran model entries. A powerful embedded search engine offers dedicated filters, to simplify the selection of design parameters and result components from the Nastran model – allowing for an effortless parameterization.

Orchestrating simulation campaigns

Optimus orchestrates parametric simulation campaigns involving Nastran, freeing users from repetitive manual model changes and data processing. Using Optimus’ Design of Experiments (DOE), Response Surface Modeling (RSM) and Numerical Optimization methods, engineering teams quickly identify product designs that meet a combination of objectives set by multiple (often competing) performance targets. At the same time, design constraints imposed by manufacturing realities or stringent regulatory and standardization requirements are consistently taken into account. 

Integration in a few clicks

Optimus automatically modifies the Nastran design parameters, updates the underlying models and extracts the result outputs (scalar and vectors) in an automated simulation or optimization process. Built on Optimus’ User Customizable Interface (UCI) wrapper technology, the Optimus interface for Nastran allows to access all advanced parameters and versions of Nastran without any configuration programming - enabling the parameterization and workflow integration of any Nastran model with just a few clicks.
