Hi all,

I used HBMAT command to obtain the stiffness and the mass matrix.

I also have the modeshape vectors (which are in ascending order of node number, obtained them using *vget) for the same problem.

My aim is to rearrange the modeshape vector in the same fashion as the system matrices are arranged, so that I can do further calculations in MATLAB.

Can anyone confirm how is the Mass matrix assembled ?
