Challenge	Northrop Grumman Systems Corporation (NGSC), a global leader in aerospace and defense technology, was facing a significant challenge in their post-processing workflow. The process involved manually calculating combined stresses from NASTRAN results, which was particularly time-consuming due to the presence of hundreds of 1D beam elements with varying cross-sections in some system level models. Each type of 1D beam required its own set of calculations. The challenge was to automate this workflow to save time, minimize errors with simple user inputs, and scale the process to allow a variety of models, such as different cross-sections, to be post-processed.

About Customer	Northrop Grumman Systems Corporation (NGSC) is an American multinational corporation that is a global leader in innovation and technology for aerospace and defense. The company's marine systems division, located in Sunnyvale, CA, is a leader in the design, development, and production of advanced naval systems. NGSC is known for its commitment to technological innovation and its significant contributions to the aerospace and defense sectors. Read More
Solution	Altair and NGSC engineers collaborated to address this challenge by first discussing the current workflow, identifying pain points, and sharing necessary materials like equations, sample NASTRAN model, and results. Altair Compose was chosen as the solution due to its extensive library of FEA results readers, developed for Altair HyperView and Altair HyperGraph, and the community's familiarity with the Open Matrix Language. A 'template' script was provided to the NGSC team, which read in their model and results files, modified the data as per the provided engineering equations, and output a custom results file that could be visualized in HyperView. With further collaboration, NGSC engineers were able to modify, expand, and apply the script to their production level post-processing. Read More Log in to view content

Challenge

Northrop Grumman Systems Corporation (NGSC), a global leader in aerospace and defense technology, was facing a significant challenge in their post-processing workflow. The process involved manually calculating combined stresses from NASTRAN results, which was particularly time-consuming due to the presence of hundreds of 1D beam elements with varying cross-sections in some system level models.

Solution

Altair and NGSC engineers collaborated to address this challenge by first discussing the current workflow, identifying pain points, and sharing necessary materials like equations, sample NASTRAN model, and results. Altair Compose was chosen as the solution due to its extensive library of FEA results readers, developed for Altair HyperView and Altair HyperGraph, and the community's familiarity with the Open Matrix Language. A 'template' script was provided to the NGSC team, which read in their model and results files, modified the data as per the provided engineering equations, and output a custom results file that could be visualized in HyperView. With further collaboration, NGSC engineers were able to modify, expand, and apply the script to their production level post-processing.

Impact #1	The implementation of Altair Compose in NGSC's post-processing workflow resulted in a number of qualitative benefits. The solution was able to quickly read FEA results, process and manipulate the data based on defined operations, and output new results. These results could also be visualized in other Altair solutions like HyperView or HyperGraph. The solution addressed all of the identified pain points and goals. Moreover, the script provided is editable, making the solution repeatable and allowing errors to be more easily identified. The success of the solution was largely due to the clear identification of pain points and objectives, the early identification of the correct solution, and the regular communication between Altair and NGSC engineers.
