Dear nI thanks again for your reply. Like you said, I would be requiring the stiffness matrix as well as the mass matrix, not the entire matrix at all the points, but only at some critical locations of the beam. That is why I considered the reduced model approach. I was not able to extract the matrices using the APDL commands. Hence as an alternative approach, I tried with the manual method of calculating stiffness using F = kx. But you made me realize the mistake.nIt would be really nice if you can guide me the best approach. I would want to use the reduced values of the matrices in Matlab for developing the flexibility of the beam.nnThanks and RegardsnGoutham Sajjan
