PARAM, EXTOUT

Bulk Data Entry EXTOUT controls the output of reduced matrices to external data files for use in subsequent analyses.

Parameter	Value1	Value2	Description
`EXTOUT`	<DMIGPCH,DMIGBIN, DMIGOP2, DMIGOP4>	<DIGITS> Default = 16	DMIGPCH (Default) The matrices are written to an ASCII .pch file. DMIGBIN The matrices are written to a binary .dmg file. DMIGOP2 The matrices are written to the .DMIGOP2 file. This option is only available for CMS Super Elements. This output is not supported for static reduction. This is a binary file. The mass, stiffness, viscous damping, and structural damping matrices, as well as the interface GRID and components are written to the .op2 file. DMIGOP4 The matrices are written to the .op4 file. This option is only available for CMS Super Elements. This output is not supported for static reduction. This is an ASCII file. The mass, stiffness, viscous damping, and structural damping matrices are written to the .op4 file. The OUTPUT4 FORMAT is 1P,rEw.d where d=DIGITS and w=d+7. The number of columns is the integer portion of r=80/w. So, the default value of 16 gives the format 1P,3E23.16. Additional files with the extension .USET are written. This file contains the USET U1 data for the connection points as well as SPOINT data for the modal degrees of freedom. Refer to Direct Matrix Input (Superelements) in the User Guide for more detailed information.

<DMIGPCH,DMIGBIN, DMIGOP2, DMIGOP4>

Default = 16

DMIGPCH (Default): The matrices are written to an ASCII .pch file.
DMIGBIN: The matrices are written to a binary .dmg file.
DMIGOP2: The matrices are written to the .DMIGOP2 file. This option is only available for CMS Super Elements. This output is not supported for static reduction. This is a binary file. The mass, stiffness, viscous damping, and structural damping matrices, as well as the interface GRID and components are written to the .op2 file.
DMIGOP4: The matrices are written to the .op4 file. This option is only available for CMS Super Elements. This output is not supported for static reduction. This is an ASCII file. The mass, stiffness, viscous damping, and structural damping matrices are written to the .op4 file. The OUTPUT4 FORMAT is 1P,rEw.d where d=DIGITS and w=d+7. The number of columns is the integer portion of r=80/w. So, the default value of 16 gives the format 1P,3E23.16.; Additional files with the extension .USET are written. This file contains the USET U1 data for the connection points as well as SPOINT data for the modal degrees of freedom.
