Dear Daniel Thanks for the reply. I missed to reply to your comments. On your comment on solving: << This are nmx different calls to NDSolve that are completely independent. Say im==1, then bdefmitr[[im]]==vi[1][t]. That is, you are declaring that there is only ONE function to solve for. My reply: Yes, I am solving them 'nmx' times (nmx = max mode of significance, and im = 1, 2, ..., nmx defines the individual mode numbers), and I am obtaining the time response for each modes separately. Later I combine these time response using mode shape function (Sin[im pi normalizedpositionvariable]) to get the displacement response over time. Your example is helpful, and I will update my problem if I find something. Thank you. Regards, Gopinath
