10.6 Solution of Full-Potential Equation (tsd.c)

Generate executable tsd on unix by using cc -o tsd tsd.c -lm
Test Cases with PC executable tsdPC.exe
NX = 101, NY = 41, Minf - 0.7, Relax_factor = 1.5
1. K = 2.5, Output: tsdK2p50ut.txt and tsd2p50utRes.txt
2. K = 2.1, Output: tsdK2pl0ut.txt and tsd2pl0utRes.txt
3. K = 1.8, Output: tsdKlp80ut.txt and tsdlp80utRes.txt
