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,
