Dear Mr Nelson, I have used FlexPDE to solve electrostatic steady-state problems. In this case I have a microfluidic channel devided by a trapeziodal devision bar, deviding the channel in two sections, where as these sections are only connected by a gap in the center. I'm creating the trapeziod shape with the URAMP function, as you have showed me before, letting the two surfaces to merge. Right now I'm trying to place four electrodes on the upper and lower surface INSIDE the fluidic channels around the gap area. I gained to place them outside with a certain distance to the channel of 0.1 units. If I determine my surfaces for the electrodes within the channel a surface crossing problem starts to occur. Is there any way to get around it so I can place the elektrodes indside on the channel surfaces? As always I really appreciate your enormous dedication in this forum and would like to thank you in advance, Massimo Kubon

Lay out your regions and surfaces according to the procedure described in the Help Manual section "Technical Notes : Extrusions in 3D". You should be able to lay the electrodes directly on top of the trapezoid channels. You will need a full layer for the electrodes (which it appears you already have) and any areas where you want surfaces to merge must be bounded with a region definition. FlexPDE cannot merge surfaces except over entire regions. P.S. I was able to make the gridding errors on this file go away by increasing the mesh density using NGRID=50. |
