Program 2 : heat flow past a cylinder with Trefftz method
Heat inflow/outflow= 1.00000
Thermal conductivity= 1.00000
Number of Points P,Q= 32
Radius of Isolator= 1.00000
Radius of Sources = 0.700000

Temperatures at Boundary points:
Temperature at field point 1 = -1.99996
….
Temperature at field point 32 = -1.96546

Temperatures at interior points:
Temperature at x= 0.000000 , y= -5.00000 = 5.19999
….
Temperature at x= 0.000000 , y= 5.00000 = -5.19999
