Hi 

    I want to print complete assembeled mass, stiffness matrices  in ABAQUS. I was trying for this. I got some clue for this as follows:

*STEP
etc
etc.
*ELEMENT MATRIX OUTPUT, OUTPUT FILE=FILENAME.EXT, MASS=YES, STIFFNESS=YES, ELSET=ELSET_NAME

*END STEP

........I used the above steps but I could not print the assembeled matrices. Any body knows how to do this in ABAQUS? I want to print the assembeled matrices. Also if I am doing a Buckling analysis of a structure we get geometric stiffness. Is it possible to print complete assemebeled geometric stiffness matrix too???

        Any help file available for this print stuff???

Thanks in advance

It doesn't seem to be possible to get the assembled stffness matrix written out in abaqus. However, element matrix output can be requested tobe written to a user defined file by the use of card

*ELEMENT MATRIX OUTPUT, OUTPUT FILE=USERFILENAME, MASS=YES, STIFFNESS=YES, ELSET=ELSET_NAME

The file name should not include any extension;an extesion of .mtx is added automatically.
