I'm running CFD on a microfluidics device that I've created, but continually get "Solver ABNORMALLY TERMINATED" during the mesh generation phase.  I believe this is due to a lack of memory in the computer.  There are hundreds of very small, branching channels, and I just can't get it to work.  I've been trying different methods for weeks.  Is there any way to open up more space on the computer? Since there are so many channels, am I going to need a computer with massive amounts of RAM to compute it?  Any advice would be appreciated.

I've attached the model below.  Despite what it seems, it IS a 3D shell, it's just extremely thin (0.1 mm).
