[@mitralanka26]

Hi Dr Dalyo,
I am working on a 2-way Fluid structure interaction project related to RBC in capillaries.
I have designed a micro-scale shell RBC and a fluid medium which has diameter just above the dia of RBC.
In the transient structural analysis I have defined two fluid surface interfaces:
1. Exterior portion of RBC 2. Interior portion of RBC.
In the Fluent medium I have defined the walls, boundaries of capillary tube and cytoplasm (hollow portion of RBC) which are supposed to interact with with the solid RBC in Transient.
I have assumed that blood runs at x velocity and cytoplasm relatively at 0.97x velocity. Similarly, in transient I have 0.97x velocity, 9.7x displacement to Solid RBC
When I run the analysis by coupling both systems I receive error by doing so. But if I reduce the time step (0.0004) sec for 10 sub-steps ,velocity to 0.0000097x and displacement by 0.000097x solution runs smoothly.
Irrespective of correctness of result, Could yo please tell me why is that if i decrease the velocity, displacement and time steps there is result and why if i consider real time scenario this does not work?
Thanks

[@LMGuzz]

[@pamstone8322]

Thank you for this awesome tutorial. Very well presented.
can we find any other tutorials from you about fluid flow over ordinary shapes and also porous medium on youtube? Thanks

[@drdalyo]

Parry Pal I do not have any other videos yet, do you have a particular shape in mind? i could maybe make a video on it.

[@pamstone8322]

DrDalyO The simplest one would be a rectangle of half solid and half porous medium. This can be the start. Simulation of the following paper is also a good practice in order to compare the results:
C. Chan, E. and F.-S. Lien (2005). "Permeability Effects of Turbulent Flow Through a Porous Insert in a Backward-Facing-Step Channel." Transport in Porous Media 59(1): 47-71.
Thank you

[@abhi-lu3hv]

thank you so much .

[@ananthansp]

sir.. your video was very informative in the sense of using fluent. I need to know about how that time vs drag and lift coefficient graph are generated after this analysis. In general how to generate any property change vs time graph after a transient analysis being done .
thank you in advance

[@sichen4085]

Very helpful and clear! I am a new user of Ansys Fluent. Can Ansys Fluent be used to simulate Oscillating grid turbulence? I am guessing I can use dynamic mesh and transient analysis? Can I use steady analysis in time? Thank you?

[@muismuhtadi359]

Thanks for the video. It gives me a nice start to learn fluent.
In my research I need to know odor transport where the source is on the floor. If the odor source is assumed to be an round inlet on surface body emitting the odor, how can I create this inlet?
Thank you!

[@prakhars962]

Although I was not able to run the simulation after 0.5s, has some problem with time steps as many options have been changes in ANSYS 2020. Have to say, I learnt a lot.

[@haveanicetime]

Hello dear Dr. Dalyo, thank you very much, if we have a rotating airfoil of a vertical axis wind turbine and we select the airfoil to monitor the lift coefficient and we set the force vector (Y direction =1) as the default settings, will the lift coefficient be accurately calculated when the airfoil changes its position? will the calculated lift coefficient be always perpendicular to the drag? Thanks

[@hongxiagu4935]

Thank you for your video, and could you please give me information about the u velocity near the upper and bottom wall being almost the same as the main flow while the boundary conditions are set to wall?

[@pamstone8322]

Hi and thanks again for your wonderful video.
What if we want to put a porous cover around this circular cylinder and see how the fluid flow changes?
how we can introduce that porous cover into Ansys?
Thanks.

[@binchen773]

Thanks for the useful tutorial firstly. I have a question about the curve of the drag and lift force. I continue to run simulation by using a time step 0.01s but get a different curve for drag and lift force (between -0.15 and 0.15). could you tell me the time step size you used for the lift and drag force curves you shew in the vadio. Another thing is in the Results part in workbench, you shew a result with about 248 time step and time step size 0.01s.

[@jordanmachardy]

Thanks!!

[@mandargadkari5714]

can we rotate the cylinder & graph of coeff. of lift vs spin ratio of cylinder

can you please do the same tutorial but this time include springs for oscillating the cylinder in X,Y direction!.

[@says46]

Thank you DrDalyO. If it is possible, can you add more videos about fluent

[@drdalyo]

+Mustafa SÖYLER I will try! Thanks for watching!

[@kelvink440]

hey very nice video and good explanation as well. but one question left, i'm not an expert with fluid techniques but i know that simulation programs are made for measuring parameters.. So my question is what is the target of this work? I mean which parameter could u investigate with this simulation?

[@alpersarac235]

Excellent ! Adamsın :)

[@sadass4740]

Very nice tutorial. The best on youtube so far. Can I request you to please put a few more fluent examples (FSI kind maybe?), if you find the time. It'll be a big help. Cheers!

[@drdalyo]

+sadass what kind of FSI, like the stress results from an object under a flow field? Maybe like the stresses in a support bracket from a pipe with flow.

[@sadass4740]

+DrDalyO Yes, that would be really amazing and helpful! Stresses on an object due to the flow field. I am basically trying to learn to finally do some coupled problems of fluid structure interactions, like a body oscillating in fluid due to flow and thereby altering the flow.

[@drdalyo]

+sadass Ok I will add it to the list of videos. Thanks for watching!
