July 22, 2004, 11:52	Convergence then Divergence	#1
Ryan Guest Posts: n/a	Does anyone know why my model converges for about 125 iterations and then begins to diverge quickly? I am modeling the heating of a small spot via a laser with forced convection over the spot...I'm also modeling species transport...it seems the velocity is what diverges first...
