dear all,
I was attempting to create a flow simulation for a pump but not really sure is the setting right or not. my goal was to obtain the pressure different. Do comments. Below is the setting: > inlet define as 0 m^3/s > outlet define as static pressure > using local rotating region where the local region is disable & define with certain RPM. final result i get -ve pressure at 1 side, is this correct? For the pressure different, i have to add both or minus? Thx!~ |

Hi, in the case of your statement negative pressure shows, that the cavitation flow is presented. You should turn cavitation option on to obtain the solution.
General Settings>Fluid> and find the cavitation checkbox here

i see. Is it also related to my meshing setup as well? is there anything that i need to take note on the mesh side?
thx!~ |
