I would like to get the mass and stiffness matrices from ANSYS 11.0. I read somewhere that I can use the HBMAT command, but I am not sure how. Is there a tutorial or example I can follow to obtain the M, K, and C matrices. Thank you.

USE HBMAT command to save the stiffness matrix from ansys in the HB format. Then you can use some routines in MATLab to convert the HB matrix to a full (or sparse) matrix.
