Unphysical Velocity..? -- CFD Online Discussion Forums

July 3, 2008, 06:16	Unphysical Velocity..?	#1
sushil Guest Posts: n/a	Hi there, I am simulating a secondary clarifier model. In it to account the effect of sedimentation I am using an UDF. I have initially tried with a simple 3D domain. the UFD worked excellent, but now when I use it for my case, I am not getting proper results. solutions is not at all converging, I am getting the error as 'Floating point error'. One more thing is that I can see some unphysical velocity in the domain whic I am not at all expecting. I think probebly due to this velocity only I might be getting the error. Can Anyone Please help me..?
