How to plot the temperature at different locations in a 3d heat transfer model

Dear Community,

I am having a problem with plotting my results from the heat transfer analysis results. I am using

createpde('thermal','trasient')

to create the model for analysis.

Is there any way to plot the temperature as a function of time at different locations within the 3d geometry, such as the the geometric center? I know that there is

getClosestNode = @(p,x,y) min((p(1,:) - x).^2 + (p(2,:) - y).^2);

in 2-d geometry to get the closest node to the specified location. Is there anything similar to that for 3d geometry?

Thank you very much!
