I am working on research where I need to model part of a microfluidic chip. The overall chip measures 6mmx6mmx1mm. The part of the chip I need to model is the center 1mmx1mmx1mm. For the heat transfer in the chip, I have the top surface as natural convection and the bottom surface as insulated. For the 4 side surfaces, I need to model as if there is still the 2.5 mm of nylon (the material of the chip) past them, but I am having a hard time in the heat transfer in solids and fluids module finding the right boundary condition to do this. Any suggestions on which one to use/which values I would need for it?
