Nodal temperature

The nodal temperature can be prescribed in the first load case, with the identifier T 1, or in any subsequent load case, with the identifier T 11. 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 NV set:

NV set number T 1/11 V $T$ ; 1 component NV set number T 1/11 V $T$ $\Delta T$ ; 2 components

depending on the number of components at the node, and the set thus defined is then assigned to the selected nodes:

AS load case number /$\dots$ /N set number N node number list /$\dots$

where

  • $T~[^\circ\text{C}]$ is the temperature,
  • $\Delta T~[^\circ\text{C}]$ is the temperature difference between the top and bottom sides of a semi-loof element, see the Reference Manual.
Note
The quantity can only be assigned to nodes that have the same or a greater number of thermal degrees of freedom than the number of prescribed values. Any missing prescribed values are treated as zero.
