Several variables are defined to be used when postprocessing. They include the pressure, velocity components, and the norm of the velocity, as well as material parameters. The instantaneous intensity also exists as a variable (cwe.Ii). It is defined as

When analyzing the results from a simulation with the CWE interface, be aware of the fact that fourth order elements are used to discretize the dependent variables (as discussed in the section above). This, in some sense, means that within a mesh element, the shape function has a lot of freedom and can contain a lot of details. These details are revealed by setting a high Resolution in the Quality section in the plots. The default plots generated already have that option set. If you add more user defined plots, remember to set the resolution.
