RE: how to obtain the mass matrix ,stiffness matrix and damping matrix after model analysis in ANSYS?

Use the *DMAT-command or *SMAT-command in a command snippet in the Solution branch. Make sure that you turn off distributed solution or you won't be able to do this since the full-file containing these matrices will be split into pieces. 

!Stiffness
*SMAT,MK,D,IMPORT,FULL,file.full,STIFF
*PRINT,MK,Ksparse.matr

!Mass
*SMAT,MM,D,IMPORT,FULL,file.full,MASS
*PRINT,MM,Msparse.matr

!... and so on... use *DMAT for full matrix printout instead
