hello dear
I simulate an axisymmetric flow in a tube with dynamic wall motion. I want to calculate the pressure gradient along the tube but when I use dp/dx in xy plot, it shows me a horizontal line with zero value like the attached image so: Does anyone know how I can calculate the pressure gradient in fluent? |

hello
Thanks for your answer, your answer is good but it's good to know in fluent for plot any variable gradient you must save the value of that variable. in general fluent doesn't save any gradient so you can't plot any variable gradient such as temperature pressure or velocity. so u must change the setting |
