warning001
 

hello,every one

my inlet velocity is 0.0925 , the model size is 4.4*4.4cm, and the total channle length is 50cm, it means there is 50cm from inlet to outlet. and i use the mass source and heat source through subroutine fluinj.f, sorent.f, sorsca.f. when i calculate it, there is warning001, "fluid inflow detected at some boundries where mass fluxes forced to zero". whould you anyone who knows it tell me how to resolve it ?

thank you in advance jane

Re: warning001
 

The warning means that you probably have recirculation at an outlet boundary. If the error message appears in the beginning and then goes away, you're okay. If the error message stays for the entire run you're not okay. Either move the outlet boundary farther downstream or replace the outlet boundary with a pressure boundary.

thank you, Leo! i have try to change it to pressure bundry and modify the sweep number and under -relaxtion now it is ok.
