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!

I am writing a subroutine DFLUX, the FLUX(1) is dependent on strain and stress. But I don't know how to get the strain and stress. I use SPRINC in the code but it seems to be wrong.

The equation for the problem is
