Dp/dx problem
 

Hi, When I plot DP/dx in a laminar pipe, Fluent give me zero in all domain even if it gives me a pressure drop in Report->surface integral. Where it's wrong

Re: Dp/dx problem
 

If you plotted the dpdx from a previuosly created dat file, than FLUENT will give you zero dpdx. In this case, iterating one more step, and displaying dpdx contour again should solve your problem. HTH.
