im simulating a sensing material with 2 electrods at the side of it instead of making joule heating and heating the sensor i got an idea that i can put a direct tempeture on my sensing layer 600k and then apply a current on the electrods to see the resistance of the material
my question is : is it possible ? applying a direct temp and then do the rest and what might be the probleme of this modele ?
hello comsol ppl tysm for your replay on my last post ( the heater plate) the simulation worked on stationary , but the results are kinda wrong i've checked the boundary conditions and they worked perfectly and now i think my meshing is wrong , firstly i started by putting a triangular mesh on the face ( spiral heater + membrane first layer ( the circle)+ the face of the substrat ( rectangle ) and finishing by swept the remaning
then i changed the goemtry to reduce the boundaries from that rectangle inside the spiral into a elipse
my question is how can i make a good mesh to find some good results , all the physics is related to the spiral heater ( joule heating)
