Hello,
I am trying to determine the effect of a heat source on the direction of the fluid-movment in a regular starchip. Which modules do I have to use? Which boundary conditions?
Thanks for your help.

in principle - and I hope - just the microfluidics and heat transfer. I'm trying to model a similar problem, Marangoni flow from laser heating, and while each physics runs fine, i'm having trouble coupling the two at the moment... see the 'jet instability' for the marangoni part, which you should then just have to add a temperature dependence to the surface tension, but...
