POST

<-1, -2, -5>

Adding PARAM, POST to the bulk data section of the input deck will activate the creation of the .op2 file.

-1 creates the .op2 file with displacement results output in the analysis system and PARAM, ITAPE set to -1.

-2 creates the .op2 file with displacement results output in the basic coordinate system and PARAM, ITAPE set to 0. The GEOM3, GPDT and GPL data blocks are also included in the .op2 file when PARAM, POST, -2 is used.

-5 writes the stiffness and mass matrices to the .k.op2 and the .m.op2 files, respectively, in addition to creating the .op2 file with displacement results output in the analysis system and PARAM, ITAPE set to -1.
