I fed in a simple wave equation into comsol using it's coefficient form PDE and am trying to plot the unknown variable vs time. Can anyone tell me how to do it? The geometry being used is a simple rectangle. Comsol automatically plots the unknown variable vs the dimension of rectangle but not the time plot, not even using point plot or line plot.

In the x-Axis Data section in these plots, you can set Parameter=Expression. This way you can control what the x- and y-axes correspond to using the Expression edit fields in the x-Axis Data and y-Axis Data sections.

Hi,

Try to use Global plot under 1D plot. Select your variable under the "y-Axis Data", then select "Expression" under "x-Axis Data" and type "t".

Regards,
Dima.
