Hello everyone,<\/p>\n

I tried to simulate gravity driven fluid flow in Fluent (gravity=9.8m.s^-2, water, 1m heigh, two outlets with same pressure) and the velocity resulting was 12 orders of magnitude too low.
\"\"<\/a><\/p>\n

So I closed the outlets to see the hydrostatic pressure profile and it is also ridiculously low.<\/p>\n

\"\"<\/a><\/p>\n

Further I have a good hydrostatic profile (10^4 Pa of difference for one meter of water) with a gravity of 10^14 m\/s^2.<\/p>\n

Do you have any idea why the effects of gravity exist but are far too weak ?<\/p>\n

 <\/p>\n

Thank you in advance<\/p>\n","protected":false},"template":"","class_list":["post-290887","topic","type-topic","status-closed","hentry","topic-tag-computational-fluid","topic-tag-gravity-1","topic-tag-hydrostatic"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
