Smoke is modelled as a product polyester combustion in accordance with ARGE Guidelines

Thank you 👍

Hi Adeeb, this video is related to project. Will not be able to share code. However, I can do it for you as a separate project, let me know. Thanks

how do you model a smoke generator?

Ansys CFX

i just discover the app from smv folder. thanks btw

yes, fds is open source and its completely legal to download and use

have you solved this problem, i am facing the same problem

@@saurabhsuman9863 same problem

UVW is the vector indicating the direction of flow from the VENT. For example: &OBST XB=1.0,2.0,0.0,1.0,0.0,1.0 / &VENT XB=1.0,1.0,0.0,1.0,0.0,1.0, SURF_ID='HVAC', ID='HVAC OUTLET', UVW=-1,0,1 / The above input defines a vent lying in the y-z plane facing in the 􀀀x direction. The flow vector indicates that the flow from this vent is in the -x direction with a 45 degree up angle (the x and z components are equal in size). FDS will set the tangential velocity of the vent to obtain the specified direction indicated by UVW. This will only be done if the vent is inputting gas into the domain. Note that the values given for UVW are normalized to a unit vector. For details refer to section 12.2.7 of FDS user guide

@@StreamCFD1 thanks for your answer. In above example for a vent 30 degree up angle in vector form: Vel=[-cos(30)i+0j+sin(30)k]*velocity Vel=[Ui+Vj+Wk]*velocity is it correct?

Yes

10-1/3*22不等于0，这意味着列车不会减速到0，但是在cfx中可以瞬间减速到0吗？ 或者为什么不将时间设置为 30 秒，这样它就可以减慢到 0？

Modeling procedure is also explained in video, give it a try. In the meanwhile if I can find the file will share link.

@@StreamCFD1 did you find it friend ?

@@StreamCFD1 Thanks

I have explained everything in this video kzbin.info/www/bejne/nHPXeYlsrKaIgJY

@@StreamCFD1 You are almost or better than peacemaker or super hero but only dealt with pressure and velocity contour.

Yes it can, you can add heat generation

I don't think that's an error. I watched another video that demonstrates the flow with actual water by injecting dye, and you can see the same pools of relatively stagnant water that block the flow, redirecting it to round the corners rather than continuing in the reverse direction. And that's basically what I expected to happen; the description I've heard in other sources that say it would hit at a a near 180-degree angle really sounded very much like either an oversimplification or possibly a naive rationalization.

@@hurkyl1560 I'm not necessarily doubting the qualitative result but I looked at it frame by frame and things really move through solid walls in the video.

@Penny Lane, Yes I have observed that, actually idk why ansys discovery is ignoring that small feature, there should be some settings to control defeaturing size.

​@@StreamCFD1 I was assuming the depicted boundaries didn't match exactly the boundaries in the simulation, but I don't know the software.

there is no builtin method to run fds file by click. you have to run via command prompt

Two overlapping bodies shall be present and meshed seperately. Thereafter proceed as in video

This is done using sliding mesh. Will upload tutorial soon.

This is mixed flow inline fan, used for ducted ventilation

StreamCFD thanks.
