Floworks Accuracy

To All,

 

We recently purchased Floworks and are using it to thermally model an electronics project.  Before we start using it for any projections on this design, we're testing its accuracy on small experiments.

 

Right now I've got a 3 Ω resistor burning 3 Watts attached to a heatsink.  I've entered heat generation, thermal resistance (measured and calculated), ambient air conditions etc.

I'm quite sure I have all of the initial conditions as close to reality as possible.

Unfortunately I cannot get the results to get any closer than 10°C below what I am physically measuring (Calc = 40°C, Meas = 30°C).

 

Have any of you guys gotten floworks to produce highly accurate results (i.e. ±2.5°C) or is it always off or is there some major variable that is easy to miss that would influence the results?

 

Thanks in advance  -  Bram
