Hello,
For TACS' modal analysis, what are the output units for the modes? We're looking at nondimensionalizing the modes by the mass matrix such that
$\phi^T M \phi = I$
where $\phi$ is the resulting modes and $M$ is the mass matrix. I'm not sure if the ouptut modes are already scaled by the mass matrix, or if $M$ is able to be output for manual scaling. We're generating the ModalProblem directly from the BDF (without an elemCallBack).
