USDFLD and automatic time incrementation
USDFLD and automatic time incrementation
(OP)
I am using a USDFLD subroutine for my FE analysis. I wanted to know if I can use USDFLD subroutine with the automatic time incrementation? I have read in the documentation that PNEWDT is allowing the subroutine to work with automatic incrementation but I wanted to be sure if I need to define any number for PNEWDT or just stating it in the USDFLD interface like below is enough and Abaqus itself will take care of it?
SUBROUTINE USDFLD(FIELD, STATEV, PNEWDT, DIRECT, T,
1 CELENT, TIME, DTIME, CMNAME, ORNAME, NFIELD,
2 NSTATV, NOEL, NPT, LAYER, KSPT, KSTEP, KINC, NDI,
3 NSHR, COORD, JMAC, JMATYP, MATLAYO, LACCFLA)
...

RE: USDFLD and automatic time incrementation
Dear IceBreakerSours I am trying to use it for expanding the elements by comparing the stresses in the model to an initial stress during the step. However, I have one more issue which is reading and writing the stresses in the local direction to compare it to the initial stress, which I haven't been able to do it so far.
