How does VA One calculate hybrid TL for a DAF loaded FE panel connected to two SIFs?
Hybrid transmission loss provides an efficient way of predicting the transmission loss of a complex panel modeled in FE Structure. The main advantage is provided by the SIF and its capability to connect with FE subsystems (i.e. no modeling of the acoustic field with FE acoustics is required). How is this calculated?

Heat Sources in Sysweld
From finite element point of view, a heat source is modelled in SYSWELD by a volume density of energy named Qr (W/mm3) applied to elements, which move along the welding trajectory.

Visualize modal animation inside acoustic cavity
When the acoustic modes are animated, the default will animate the skin only, but it is possible to visualize the interior of the cavity too.
