Hi! I'm new to Comsol and I'm trying to model a microfluidic channel lying on top of a system of interdigitated electrodes in 2D. The channel has 2 inlets on the right (the top right one is for the sample and the bottom right one is for a stream of buffer solution) and 2 outlets on the left. The electrodes are supplying an AC voltage so that the cells will separate by dielectrophoresis. So far, I've modeled a stationary study just looking at the Creeping Flow physics and I'm trying to add a frequency domain step to compute the Electric Current physics for an AC voltage. However, the voltage plot I get only has the electrodes at a voltage and everything else is at 0V (attached picture). Can anyone else me figure out how to get a good voltage plot?
