This subroutine is used for nonuniform pressure, characterized by distributed load labels of the form PxNUy, cf *DLOAD. The load label can be up to 20 characters long. In particular, y can be used to distinguish different nonuniform loading patterns. The header and variable description is as follows:
subroutine dload(f,kstep,kinc,time,noel,npt,layer,kspt, & coords,jltyp,loadtype) ! ! user subroutine dload ! ! ! INPUT: ! ! kstep step number ! kinc increment number ! time(1) current step time ! time(2) current total time ! noel element number ! npt integration point number ! layer currently not used ! kspt currently not used ! coords(1..3) global coordinates of the integration point ! jltyp loading face kode: ! 21 = face 1 ! 22 = face 2 ! 23 = face 3 ! 24 = face 4 ! 25 = face 5 ! 26 = face 6 ! loadtype load type label ! ! OUTPUT: ! ! f magnitude of the distributed load
