Temperature at a certain point in a solid structure?

I am using comsol 4 and I found a model of a human body online and I have imported it into comsol. I set up the boundary conditions and get a suitable answer from the slice graphs but I cannot seem for the life of me to get a temperature profile with time of a point on the inside of the model (it only gives me the choices of the outside edges of the model and points at connections). I am using the transient model.

When I try to insert a point into the model to analyze that point, I get an error of "internal error in geometry composition."

I have tried inserting a small sphere inside of the model (to pick a point on it's edge) but I can't seem to get the continuity between the 2 objects to transfer heat within each other (the boundary is thermally insulated). Even if I put the sphere into the heat transfer in a solid it still stays thermally insulated.



TL;DR: How do I pick a point to be evaluated without putting the point on the model?



Thanks a million,
Chris Golding

Hi

in V4 you have many ways around for the postprocessing, among others make a copy of you solution (right click on data set) add a 3D point on the new copied solution set and define the coordinates of this point, then you can ask for plots or global datavariable values for this point.

Try out the numerous ways to plot the results, test the right click, there are often sublevels overlooked quite deep in the tree and the "more =>" options (or other names for grouping less used items) have many hidden jewels

Good luck

Hello Chris,
May I please know where did u get the human model and who did u import it.
I have an assignment to work on human model. Can i have the details. Thank you

Hi Chris,

Please, could you send me the geometry of your human body ? I need of this geometry to perform the calculation of the electromagnetic field scattered by a human...

Thank you
