Meshed Model CFD Grid I
Non-uniform cartesian grid
Concentrated resolution on the fingers 120x100x100=1.2
million units Finer resolution ->
better results

Current Results
Technical Issues Resolved System finally debugged Some initial qualitative results have
been obtained Pressure Distributions, Streamtraces
(streamlines) are of greatest significance at this time
Quantitative results forthcoming, require further analysis
