May 28, 2022 at 4:23 amtumulpurwarSubscriberHi , i am getting reverse flow,if i simulate external flow dynamics at pressure outlet for Multiphase flow(Air + water) under STEADY STATE..please note if i simulate thsi same problem in TRANSIENT STATE, the problem dont come more..I am curious why it is so.
I dont want to incresae more domain size to increase outlet distance...I saw in Ansys guide, information below, but this command is not able to execute if i try in my command window.
Can anyone help please.
May 30, 2022 at 7:49 amDrAmineAnsys EmployeeWhich steady state solver are you using? Open Channel flow reversal of gas phase can be physical. Generally open channel flows are inherently transient which might end in pseudo steady state .

May 30, 2022 at 9:01 amDrAmineAnsys EmployeeUse coupled pseudo transient.
May 30, 2022 at 9:01 amtumulpurwarSubscriberOK THANKS
May 31, 2022 at 6:07 amtumulpurwarSubscriberHi DrAmine
Do we just rely on COMPUTE FROM "Input", for these 2 red boxes, or do we need to put by ourself?
In case of hull, Area will be wetted surface area and Length will be length of hull..Right?
Do these reference value Solver use to do calculation?
Please if you could let me know.
Also what we have to put in red box below in Photo, i mostly put value = 1,the photo is from Ansys tutorial, why they putting -.0534..
Please if you could explain me..Thanks
May 31, 2022 at 7:30 amDrAmineAnsys EmployeeReference values are only fir post processing
May 31, 2022 at 9:14 amtumulpurwarSubscriberok thanks..Could you please answer my second query..could be stupid query but i wanted to know..thanks
May 31, 2022 at 9:27 amDrAmineAnsys EmployeeValues are nou used when solving
May 31, 2022 at 9:58 amtumulpurwarSubscriberok thanks

PSUEDO WITH COUPLED NOT WORKING EITHER IN STEADY STATE CASE....NOW I AM USING TRANSIENT ANALYSIS...WOULD YOU LIKE TELL ANY MORE SOLUTION IN WHICH IT CAN RUN IN STEADY STATE?..thanks

Can you tell, i have 4 core fluent license, how much maximum mesh element size commercial Ansys fluent can accept?
