thread799-27257: Can ABAQUS do base excitation vibration?
I would like to run an ABAQUS Random Response analysis multiple base inputs. The info from derickdfc (previous post) covers the single PSD spectra input, but I have a mix of nodes with very high levels and others that are low. Unfortunately this option:
*BASE MOTION, DOF=2, LOAD CASE=2, BASE NAME=LowMotion
is flagged as an error in ABAQUS if setup identical to the modal solution MulitBaseMotion01.inp.
So what is the method to let ABAQUS know that there are 2 different sets of loaded nodes?

I still need a method that will work with multiple base motions since the input is coming from the mounting base. And in this case, the "base" is different pieces of structure with different levels of excitation input.
