Heat flux problem with HETVAL and DFLUX

Hi,

I am using HETVAL in abaqus to generate the heat. I am testing my subroutine and I set the flux(1) to a constant, like 5000000, but the output 'HFL', which I think should equal to the flux(1), turns out to be a very small number, and also it is a linearly increasing curve w/ time. Thus, the temperature is nearly not increasing.

I am also using the same problem using DFLUX.

Can anyone help me out?

Thanks!
