Boundary table problem. Thanks for help
 
Hi, I am building a tubel model with an orifice in the model for jet flow study. Right now, i am using boundary data from Magnetic Resounance Imaging(MRI) scanning. There are lot of negative velocity in MRI scanning at the boundary. But star_CD automatically omitts the negative velocity. So, after the running, I find that the velocity at the orifice in star_cd model is almost ten times larger than actually MRI model. So my question is: Has anybody met the similar problem? and what is the possible solutions for this problem?

Thank you in advance. Longchuan
