Translational Motion
This subnode provides movement by translation to the model for heat transfer in solids. It adds the following contribution to the right-hand side of
Equation 14-8
, defined in the parent node:
The contribution describes the effect of a moving coordinate system, which is required to model, for example, a moving heat source.
Special care must be taken on boundaries where
n
⋅
u
trans
≠
0
. The
Heat Flux
boundary condition does not, for example, work on boundaries where
n
⋅
u
trans
<
0
.
Domain Selection
By default, the selection is the same as for the
Solid
node that it is attached to, but it is possible to use more than one
Translational Motion
subnode, each covering a subset of the
Solid
node’s selection.
