This App is for the calibration and validation of finite element (FE) models
to match data from vibration tests. It uses a metric based on estimates of
frequency response function to do the calibration. It supports FE models
built by use of Nastran and Abaqus besides Matlab models. Also the code
StructDyn (included in distro) is supported. Four test examples of increasing
complexity are included. These range from a simple 6-dof problem to a satellite
problem involving more than thousand degrees-of-freedom.
Documentation is provided to get you started. The theory is described in a
paper available from the Help menu.

NB! If you have not heard of structural dynamics modeling and experimental
modal analysis (or system identification) before, you should NOT try this
software. However, if you are interested in the model calibration/validation
problem in structural dynamics, a try is probably worth the time spent.
