Aeroelastic Optimization Setup

Hi,

I am attempting to set up an aeroelastic optimization within HyperStudy. Although I am having trouble setting up responses involving the damping and frequency values provided from the Flutter Analysis output file *.FLT

I want to monitor all the modes within the *.FLT file and check for Static Divergence and Dynamic Flutter. As a result, I would like HyperStudy to read the entire columns of Damping and Frequency values for a given Mach number and Density ratio. The Hyper Study built-in Data Source extractor does not recognize the *.FLT file and as a result forces the reader Tool to "ASCII Extract". I could not figure out a way how to read vectors of data using this Tool. The best I could achieve is single values across all the modes aka a vector size [1,n] where n is the number of modes.

Does anyone know how I can achieve this? or Know of a better way to set up an Aeroelastic Optimization within HyperStudy?

Regards,

David

I have attached a simplified FEM of a cantilever plate with a PK Flutter analysis setup. If you want to give it a try.
