New Annotation Plots

Annotation plots, new with COMSOL Multiphysics version 5.2, can be used for displaying customized text in 2D and 3D plots. This functionality is found under More Plots in the Add Plot section of the ribbon. Simply define the location and text for the annotation. The text can include the results from evaluating expressions by typing in eval(expr). The software will automatically grab the value and insert it into the text.

New Smith Plot Group

COMSOL Multiphysics version 5.2 contains a new Smith plot group, where you can plot impedance, admittance, and reflection data in a Smith grid. Smith plots are useful for relating complex valued S-parameters (reflection coefficients) to input impedance, or to admittance of antennas, transmission lines, and other network components.

New Octave Band Plot Feature

Measurement tools showing both a sound pressure level response and material data, such as absorption coefficients, are often displayed in frequency bands as well as in a weighted dB scale. The new octave band plot is used for representing simulation results in the same manner. The plot uses octave bands or 1/3-octave bands to show the decibel scale over the specified frequency range.
