Hello
I simulated laminar fully developed flow in curved pipe (3D) and I need to calculate pressure at each surface along the curved pipe.
for this reason I need to use UDF?
Can you help me? or have any example about this problem?

why do u want to use a UDF for calculating pressure drop, you can directly get the pressure values ai inlet n outlet from surface integrals. Ryt..??

Thanks for your answer but i want to plot pressure vs distance of curved pipe.
like attached picture.
for this reason I need to calculate average pressure in each section and along the curved pipe.
