Floating point error -- CFD Online Discussion Forums

July 14, 2004, 14:56	Floating point error	#1
Chico Mbanu Guest Posts: n/a	Greetings, I am trying to model 1/4 of a D circle with an inlet and outlet. In addition I have two smaller cylinders in the quarter circle that act as tubing for oxygen diffusion. These tubings both have inlets and outlets and the portion that is inside the quarter circle I have given a wall boundary condition so I can add a diffusion coefficient for oxygen. The problem that I am having is that when I run the simulation I get a "floating point error (imprecise)" or a "floating point error (underflow)". I am not sure what this means or how to go around it. If you have any suggestions, it would be greatly appreciated to know of them. Sincerely, Chico
