Shear force wrt a local coordinate system in abaqus

[ardalansv]

Hello
I want to obtain the shear force with respect to a local coordinate system in a set of elements in Abaqus? What output should I ask for?
I used NFORC output but in the ODB when I change the Coordinate system the NFORC1, NFORC2 and ... values are not changing.
Please help me to get the shear force in a set or surface made of 3D elements.
Regards,
Ardalan

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)
...
