Hi,

I have some problems while using COMSOL4.4 to simulate model. I try to build a model that place a tungsten wire (d=0.1mm) in a water sink and apply 1 volt on the wire for 10 seconds to find out the maximum temperature. I applied electric potential and ground on the wire in the joule heating module, added heat transfer in fluid for the water sink in heat transfer module. The result is 278 degC which is much higher than the experiment result. I don't know where is the problem, can anyone help me ?

Thanks!
