hello my friends
I am trying to generate a linear (regular sinusoidal) wave in flow-3d
the wave specifications are as follows:
wave period: T=2.04 sec
wave amplitude: H=0.26 meter
water depth: h=3.5 meter
with above specifications, the wave length computed as 6.27 meter.
the flume length is: 31.35 (=5*6.27)
height of flume is: 5 meter
165 and 85 cells were generated along length and height of the flume respectively.
RNG turbulent model was selected.
I also checked the following box at the outlet boundary condition:
allow fluid to enter at outlet boundary
flow-3d version 11.2 was used
but as you can see, the generated wave is very unpleasant
could anybody please tell me "WHERE I WAS WRONG ?!"
thank you in advance

Hi, thank you for answering
yes, that is exactly the wave I would like to generate
Would you like me to get screen shoot from other setup windows of flow-3D ?
Or, If you give me your email, I could send you the flow-3D file.
This is my email: mahdy.pars@gmail.com
Thank you in advance

سلام
مشکلت حل شده؟
به نظرم بهترین کار اینه که اول یه چندتا عکس از مراحل ساخت موجت بزاری تا معلوم بشه کجا اشتباه کردی
