For obtaining Mass and Stiffness matrix

[Abhinaya]

Dear Sir,

Could u please tell me how to use the HBMAT command in ANSYS?And in
which format would I be getting the matrices. Compressed column
storage?
And please mention the output mode of SPMWRITE command aswell.

HBMAT writes matrices in the Harwell-Boeing format, see for example

http://people.sc.fsu.edu/~jburkardt/data/hb/hb.html

HBMAT writes the matrices from the FULL file, for example

/aux2
file,file,full
hbmat,K,,,ascii,stiff,yes,yes
fini

You can also look at Math-APDL.

SPMWRITE writes a text file with the reduced matrices and the file
should be understandable.

Basically make an example, read Help and try it. This is the best way to
learn.
