hello
how can one calculate the reaction heat at nodes with a fixed temperature (=nodes which have a Diriclet boundary condition)?
I tried to get it with the surface energy balance keyword, like this:
/BILAN FLUX SURFACIQUES= 12
where 12 is the reference (group of face elements) of the conduction mesh to which the Diriclet condition is applied.
But the result is zero. It seems that /BILAN FLUX SURFACIQUES works only for other types of boundary conditions like heat exchange, radiation etc.

added 01. Sept , one more question:
(A)
how can I get the heat which passes through a certain section of my model? It seems me rather cumbersome to evaluate the heat flux at this section and to integrate it with the section area. What I tried instead:
I partitioned the mesh in 2 contacting parts, in syrthes I defined a contact boundary condition (with a property which influences only very little the heat flow). Then I included
/BILAN FLUX SURFACIQUES ref1
/BILAN FLUX SURFACIQUES ref2
where ref1, ref2 are the references of the 2 contacting boundaries. But the output is zero!!
can somebody please give me a good advice?
(B)
in the user manual (version 4.1) I find the keyword
ECRITURES OPTIONNELLES RAYONNEMENT= OUI
for output on the radiation mesh.
But syrthes 4.3 does not accept that keyword, it answers "unknown keyword".
Has it been substituted, and by what?
thank you
