Re: Gray radiation error

Yes I believe that is correct. Perhaps if the radiation is normal and the surfaces are at right angles they do not see each other.

Doesn't this surface radiate out away from the body. The heat flux should be applied to this surface, travel through the body and radiate out the other side.

You may be interested in section 18.3 of the Elmer Solver manual where you can write your own user functions

Looks like Z flux density is 1 except for the boundaries

Re: Run the sif file by ElmerGui Windows

you don't have a
ELMERSOLVER_STARTINFO file
the ELMERSOLVER_STARTINFO
lists the sif file to run, in ElmerGUI you have to save project to get one prior to running
from the command line you can execute a sif by typing
ElmerSolver mycase.sif

without having a ELMERSOLVER_STARTINFO file

Re: Heating a metal wire

Yes I agree the heat equation has to have a boundary condition, but a specified temperature conducts into the metal which is not the intent in this case.

Re: Heating a metal wire

I think the heat equation is going to take the 800 degree boundary condition and conduct heat into the wire, until the whole wire gets to a steady state of 800 degrees. If you only use the heat equations that is what happens. I took the specified temperature off and set it to radiate heat out of the...
