CGWAVE...I don't know whats causing this error in Wave Modeling Posted March 5, 2009 · Report reply Well I found out what was causing my error. When I chose a coastline depth, I chose a depth that lied to close to a singularity. The singularity caused interpolation in the bathymetry, which overlapped my coastline arc. I then forced the depth to my desired value not thinking anything of it, which resulted in depths within my doimain less than the value I assigned. I'm assuming this caused some numerical problems along the way. Just thought I would give some feed back since you were so helpful with me. Thanks again.
