Interpolatetemperature produces NaN inside domain

Hi,

I have solved a thermal pde on a rectangular domain sucessfully.

However when I want to evaluate the solution at intermediate (horizontal) lines, for some values the result is NaN. The query points are all inside the domain on which the pde was solved. If I move the line by approx. 0.2 * Hmax the result is valid.

From the documentation I dont see how this can happen, as NaN should only be returned if the query points are outside the domain.

What could be the reason for this behaviour?

Thanks

Tobias

As you mentioned the interpolateTemperature function only returns NaN when the query points lie outside the domain. Can you provide the data of your solution from thermal pde?
