attached you find your input files. I found following errors in your model:

*.mmp - error with $HEAT_DISPERSION input

*.gli - better add all points to your POLYLINE

    *.st - you don't need a source term if you have a constant temperature at domain bottom (if I understood your setup right)

    *.out - you can use $ GEO_TYPE DOMAIN if you want to output your variables for all nodes

Hope this helps.

Best

Aaron

Hi Aaron/Mohammad/Nori,

Thanks a lot for correcting my input files.

I run the simulation and it worked.

However, the result for the first step (i.e initial conditions) gives strange temperature values (view HK1_HEAT_TRANSPORT0).

I am expecting the initial temperature to increase linearly from 25 to 85 degC (from the surface to the bottom) but I it seems I got something different.

Attached are the result files. Please let me know if you have an idea about it.

Regards,

Guillaume

Hi,

you should set parameters of $DIS_TYPE GRADIENT as

GRADIENT reference position, reference value, gradient

BTW, as you are solving a steady state problem, I.C. has no influence on it.

Only B.C. matters.

Best,

Nori
