Hi,
I use COMSOL to simulate a microheater to heat the polymer waveguide on Silicon substrate.
The model is 2D. Silicon substrate serve as the heat sink at 25 degrees. When I set the microheater to 300 degrees, I can get a right a temperature distribution.
But now I want to set the microheater as the Heat source,and use the general source as 1000 W/m3. I set Bottom boundary at 25 degrees, and other boundaries as the Thermal Insulation. I can't get a right temperature distribution.
Can any experts on COMSOL tell me the reasons? Very urgent! Than you!
The version is Comsol 4.2.
