Thermal line (3D) / point (2D) region
Introduction
The line (in 3D) / point (in 2D) regions are:
-
either material regions: used to model filiform regions in the study domain
-
or regions known as non-material region: used to impose boundary conditions (BC) inside or on the frontiers of the study domain
Material regions (filiform regions)
Filiform regions enable the modeling of conducting regions of small cross-section.
The filiform regions are described in the same way that the massive regions, with, in addition, the cross section of the region.
In 3D, the direction of the thermal flux is imposed by Flux. The thermal flux is usually considered tangent to the line that models the filiform region.
Non-material regions
Non-material regions enable the imposing of boundary conditions (BC).
