Other Results Plots, Datasets, and Derived Values
A variety of dedicated postprocessing tools are available with this physics interface. They are listed below and referred to in the COMSOL Multiphysics Reference Manual.
Sound Pressure Level on Surfaces and in Cross Sections
The sound pressure level on surfaces is plotted using the Sound Pressure Level Calculation subfeature to a Wall node.
The SPL can also be visualized on an interior cut-like plane by adding a plane in the geometry, meshing it, and then apply a wall with the Wall condition set to Pass through. In this way the boundary will only be used to map the SPL and will have no influence on the ray propagation.
