Edge heat flux

The heat flux at the edge of an element can be prescribed in the first load case, with the identifier T 4, or in any subsequent load case, with the identifier T 14. In the first case, the prescription applies to the entire process under consideration; in the other cases, only to the load case in which it was declared.

In the name.iB file, a vector is first defined using a LV set:

LV set number T 4/14 V $\dot q$

and the set thus defined is then assigned to the edge of the selected elements:

AS load case number /$\dots$ /L set number E element number list L edge number /$\dots$

where $\dot q~[\text{W}/\text{m}^2]$ is the heat flux.

The dimension of the quantity follows from the nonzero thickness of the semi-loof element (the edge has an area dimension). For edges and their local numbers, see the Reference Manual.

Note
The components of the vector can depend on the global coordinates $x,y,z$, using any of the available functional dependencies, see the Reference Manual.
