CST2013: Thermal Loss Distribution Specials

Simulation: Sources and LoadsThermal LossesSpecials

Consider Surface losses on boundaries

Select the boundaries, where surface losses should be taken into account.

Default conductivity for PEC

Define the default surface conductivity for the surface loss calculation on PEC surfaces. This setting has a great influence on the calculated loss power.

Minimum relative conductance for loss mapping

This settings defines the relative minimum conductance of a region where loss distributions are taken into account. Especially for surface losses this setting is important, to prevent artificial heating on curved surfaces.

The minimum conductance value is calculated by multiplying the entered relative value (between 0 and 1) with the maximum conductance value used for a certiain example:

Example: Three thermal conductance values have been used:

• Air  with 0,024 W / K /m

• Copper with 401 W / K / m (maximum value)

• Rubber with 0,16 W / K /m

If a relative value of 0.01 is specified, losses are only taken into account within regions with a thermal conductance of more than 401 * 0.01 = 4.01 W / K / m. In this case this means that losses which have been mapped to air or rubber regions are not used for the thermal simulation.
