## User-defined output

Output to file (.dat or .frd file) is governed by the *NODE PRINT, *EL PRINT, *NODE FILE and *EL FILE keywords and the FREQUENCY parameter on each of them. Each time output is written a user routine uout.f is called as well. The routine uout delivered with CalculiX is empty, however, the user can use this routine to print user-defined output to any file. This especially applies to output the user generates within other user-defined routines. The information can be made available through commons (FORTRAN77) or modules (FORTRAN90).

          subroutine uout()
    !
    !     This routine allows the user to write user-defined output
    !     to file. The output can be brought into the routine by commons
    !     (FORTRAN77) or modules (FORTRAN90). The file management must
    !     be taken care of by the user.
