I'm trying to learn the PDE toolbox. I've done a thermal analysis on some simplified pipe with some material around it One side is insulated and another is at a constant temperature. I just played around with some stuff so don't rea into what the hell this is supposed to be. This is the geometry and model:

This is all good, however, I'd like to make a 2d plot of the temperature with the wall at the x-axis and the temperture on the y-axis.

This plot is the above plot, looking along the z-axis in the negative direction. So down upon the plot.

So if I wanted to plot the temperature along thoes drawn lines for instance, how would I do that?

I tried extracting the nodes at the lines, but they are ovbiously not numbered in an order that will fit my wall thickness. Another issue is that the nodes aren't really "aligned" with my lines, so I can't get a very nice plot because the nodes will be far apart. Therefore, I can't just select the nodes and make a wall thickness using linspace and plot thoes vectors against eachother.

Does anyone know how to do what I'm trying to achieve, and is there a built in function to solve it?

Either way, thank you very much in advance!

Best regards,

Niclas
