Plotting Variables and Surfaces

Please login with a confirmed email address before reporting spam

I solved a model that consists of a tube with a perforation. The default output from COMSOL is to plot the velocity magnitude. I would prefer to plot the flow rate. How do I go about doing this? Also is there any way to select a surface to plot from the existing geometry? Ultimately, I want to determine the flow rate from the perforation and would like to select only that surface.

Hi,

Off the top of my head I would define a variable as the surface integral of velocity (=flow rate) and then create a surface in the data set selecting the face you need, then you may create a 2D plot on the newly created surface-data set and under it you may create a surface plot selecting the above mentioned variable.

Cheers
