I am modelling microchannel water flow through a glasssubstrate. The substrate is heated from the bottom. I am confusedabout setting the temperature at the velocity inlet and thepressure outlet. No matter what I set it at, the calculatedtemperatures at those faces are completely different. I would thinkif these are real temperature boundary conditions then the faceswould be forced to those input temperatures. Am I over constrainingthe model because all of the outside walls have thermal bcsalready?

Hope someone can help me out with this.

Cheers,
