    Extracting matrices from MSC Nastran/Patran (Circulatory, mass, stiffness, gyroscopic)

    I am currently using MSC Nastran and Patran rotor dynamics for my thesis and require the following matrices to be extracted for use in MATLAB: [KC]R = Circulatory matrix due to damping in rotating frame. [KC]S = Circulatory matrix due to damping in fixed frame. [G] = Gyroscopic Matrix. [K] =...
