Dear Comsol community,
It is of interest to excite a plate at each node with an imported matrix that is interpolated. Using the bracket random vibration model as reference -ref, for the procedure I define the interpolation as input in the RO model. The model uses shell elements and by so I apply a face load to the surface. As described in ref I run a rvibr study before defining the PSD characteristics. Though the calculation runs without a fault there is no rom defined in global parameters ROM.rvib (image) so as to define random vibration characteristics. The interpolation - a force over space type, is working by the way. Any thoughts?
Thank you for your time.
