[QUOTE="Arjan82, post: 6808606, member: 177647"] Allright, apparently the documentation of Ansys is also a mystery for me, the answer is just right in there 😆. Also, I'm overthinking things, as usual 🤔 The modal mass is simply $$ m = \left\{ d \right\}^T \left[ M \right] \left\{ d \right\} $$ And the kinetic energy $$ KE = \frac{1}{2} m \omega^2 $$ [/QUOTE]
