Radiation

class pyccx.bc.Radiation(target, epsilon=1.0, TAmbient=0.0, name=None, amplitude=None, timeDelay=None)

Bases: BoundaryCondition

The radiation boundary condition applies Black-body radiation using the Stefan-Boltzmann Law, \(q_{rad} = \epsilon \sigma_b\left(T-T_{amb}\right)^4\), which is imposed on the faces of boundary elements (correctly ordered according to Calculix’s requirements).

Ensure that the Stefan-Boltzmann constant \(\sigma_b\), has consistent units, which is set in the SIGMAB. This BC may be used in thermal and coupled thermo-mechanical analyses.

Attributes Summary

ambientTemperature	The ambient temperature \(T_{amb}\).
emissivity	The emissivity value \(\epsilon\) used for the Radiation boundary condition

Methods Summary

type()	Returns the BC type so that they are only applied to suitable load cases
