We are working on a SaaS version of our proprietary analysis tool NEDA. As a cloud-based SaaS, users will be able to carry out analysis without having to worry about machine performance. In addition to the licence fee, we are considering a pay-as-you-go system based on the amount of cloud computing resources used.

Dynamics of deployable flexible structure

Making NEDA available as SaaS will enable all users, not just those in the space sector, to perform static, dynamic and natural vibration analysis of deployable flexible structures. We believe that this will be a very powerful tool for the study and design of future structures.

In general, when analyzing deployable flexible structures, the equations of motion to be solved are stiff equations. These stiff equations of motion are highly numerically unstable, and conventional CAE software is very difficult to use, with numerical divergence occurring in the middle of the calculation.

The NEDA we have developed uses the Energy Momentum Method, which is unusually stable when analyzing deployable flexible structures. In fact, NEDA is a proven analysis tool in actual aircraft development, as it was used to simulate the membrane deployment of the small solar power sail IKAROS, launched in 2010.

Report function

We believe that the results of NEDA analyses should be easy to understand for all users. In particular, deployable flexible structures are very niche structures, and even engineers who have been involved with deployable flexible structures for a long time often has a little bit difficult in the analysis result. As it is such a difficult structure, we plan to provide a function that outputs a report with easy-to-understand summary of the points to be considered.
