I am trying to simulate a 3D EDL in a nano channel tube. I set artificial conditions: negative surface charge density to the tube surface, no flow condition ( dP=0, dV=0) for the inlet and outlet, one specie (z=+1). The three physics( creeping flow, electrostatic and transport of diluted species) are based on case in the COMSOL blog within this link: www.comsol.com/blogs/modeling-electroosmotic-flow-electrical-double-layer/
But I can not get the system converge. And setting up non zero dP and dV seem do not help. I do not know if there is anything wrong with my model. Hope someone could help me.
Thank you.
