Difference between INT1 and TimeHistP Calculator
 

Hi everyone,
I have a couple of variables of my model that I want to integrate against time, so I create a 'code' in APDL that deposit every value as a variable and then integrate and add it into a table. But when I apply the command INT1, with my variables the integral is ZERO.

So I tried to use the calculator (With the same variable, and integrating it against time) and actually gives me the right value. By that point I think "Ok let me check the Help to see how the Calculator makes the integral"... And basically the help said: the calculator use the command INT1 to solve the integral.

So, I tried with a bunch of variables, and trying to integrate them against time or other variables (i.e: strain), but the problem keeps happening... I'm really out of ideas...What do you think that I'm doing wrong?

The 'code' is something like this:

Nelem=2000
*DIM,ARD,TABLE,Nelem,HEAT
*DO,I,1,Nelem
esol,2,I,,S,X,SXX
INT1,3,SXX,TIME,ESF
ARD(I,0,1)=I
ARD(I,1,1)=ESF
*ENDDO

Thank you for your ideas
