Hi
I did a Frequency analysis in Abaqus. And in next step i create a Modal dynamics to analyse a harmonic pressure which is function of position and time thereafter i used of DLOAD subroutine but my problem is TIME and KINC variables of DLOAD subroutine does not change never and TIME(1) and TIME(2) are equal to "Time increment" of step always and KINC is equal to 1.
Dear Milad,
Could you share your DLOAD file? so I may help you with the time problem!
Thanks Mr Malekan
SUBROUTINE DLOAD(F,KSTEP,KINC,TIME,NOEL,NPT,LAYER,KSPT,
1 COORDS,JLTYP,SNAME)
C
INCLUDE 'ABA_PARAM.INC'
C
DIMENSION TIME(2), COORDS (3)
CHARACTER*80 SNAME
W = 1200
THETA = ATAN(COORDS(2), COORDS(1))
F = 0.85 * COS(2*THETA - W*TIME(1))
write (6,*) 'SNAME=',SNAME(1:15),',F=',F,',TIME(1)=',TIME(1)
1 ,',TIME(2)=',TIME(2)
RETURN
END
This might not be of too much use, but isn't it possible that you just have a very large model, and you are still writing out the time in the first increment just for every node? Dload should cycle through all nodes/elements etc in my understanding. So if you wait, you should see going to increment 2 and different timestep?
Is this of any help?
Dear Milad,
KSTP returns step number corresponding to your modal analysis?
Thanks David Sziroczak , But analysis has been completed butTime vars does not change.
