Hi Nalin2021 the MAPDL Theory Guide gives the details but the QRDamp solver does not create the damping matrix per se.  It first solves the undamped system then does a correction.  Anyway you can use wrfull,1 to stop the solve process after writing the full file along with changing to the DAMP solver via the modopt command.  Then change back to the qrdamp, and turn solving back on with wrfull,0 and perform the full solve.
