Thanks for good video. At 04:46, I wonder why the aspect ratios of the automatically generated meshes are not uniform though the geometry is just a rectangular surface. Can you explain? Thank you.
It might be seen as rectangular to our eyes, but if you zoom more into these cells, you might observe the sides are not perfectly perpendicular to each other, which has resulted in such aspect ratio.
You need to create the geometry like that, it means , if you want the top wall to be the axis you need to draw the rectangle in the 2nd quadrant, the axis line you want to create must be on the x or y axis.
@AnsysTutor ahhh understood!!! Very nice answer.Thank you. I wanted to say two things : 1. i am accessing ansys with a virtual machine and the black screen issue at post cfd processing is arising. I watched your video and tried to update the graphic card driver but it didn't work. My VM is a N series which is made for high graphics workload. I don't know how to fix it. 2. Please make complete tutorial from geometry to simulation video recording for heat and species transfer.
Hi. Do you have or recommend any resource material on defining the price for a simulation/modeling consulting service? I am lost. Should I price it hourly ? Thanks.
I am doing a 2D rectangular flat plate ( zero thickness) for blood flow through an artery. the only boundary conditions available is the inlet velocity at 0.23 ( Uavg) and the outlet pressure at 0. in terms of the boundary condition section can you guide on the selection I should make on outlet condition. the Umax is supposed to take an expression Umax = 2 x Uavg.
supposed I want to replace the inlet velocity function with Umax = 2 x Uavg, how do I go about this"?. the parabolic function you used for the velocity profile is it the same as the above equation
I need those piano songs to study my other subjects, they are very effective for understanding hahaha where can I find the same melodies? thank for your tutorials :)
As the initial simulation provides results for only half the pipe? Do the results then need to be doubled or is this the results for full pipe but only shows half in the image?
Its for the full pipe. As you can see, there is an axis boundary condition provided in BC. Which informs the solver regarding the continuity of the pipe.
You need to add the Reynolds number option from the data file quantities ,then you can get the Reynolds number at any location in this flow domain. After initialisation, file menu-> datafile quantities> additional quantities-> Reynolds number.
I think you have skipped the part of the tutorial where I had selected one wall as Axis. and selected the Axisymmetric analysis. In 2D geometry we generally create the half section of the part which is the rectangle.
Ansys-Tutor But the half section of the pipe need (r,theta) ? You draw the rectangle using (x,y)! In another tutorial when you for 3D pipe you used circle to create shape
You cant find the option to draw using r, theta in ansys , only there is Cartesian coordinate in ansys design modeler. The model gets converted to polar coordinates in fluent whenever you select a Axisymmetric solver type.
Nice but only one problem in the beginning properties tab don't appear on RHS. We need to click on LHS icon down arrow and then on properties to start the video.
please help me out! I'm getting floating point exception error no matter how many times i try...please let me know how to overcome that error...and where I'm going wrong!
Ram is not an issue. There might be problem in boundary condition or material assignment. Another thing might cause this problem if you want to do a vertical flow along y axis with an axisymmetric model setup.
I am looking towards simulation of circular microchannel and i created the geometry and mesh in micrometeres. Now in Fluent solver, micrometers units is not there and now will i have to put scaling factors and then scale or if mesh and geometry are already in microcmeters,Fluent directly keeps the domain extents in 10^-6. So what should i do? If already in domain extents by keeping the units metre, its already in value of 10^-6, do i need to scale again or leave and continue? It is also showing solution is converged? Is it sue to the small dimension? Please give me idea.
you have put in set-up operating pressure:101325 Pa, gouge pressure inlet and outlet=0 and initial velocity:0,0005 m/s. why the velocity grow up? i do not have any difference pressure in the boundary conditions...
Its calculated using the relation Re= rho× V× Dh/ miu. You can get the values of rho (density) and miu(viscosity) from the fluent material database table.
I followed all the steps accordingly, but unfortunately, it shows an error while starting the setup like No error handler available Error: Cortex received a fatal signal (SEGMENTATION VIOLATION). Error Object: (). any solution
I need to model a water tank tower and the base of tower has earthquake as harmonic displacement (for eg. 200mm*sin(omega*t)) can I model in fluent? I am trying to model in fluent but water has not any inlet and outlet. Can you help me in modeling?
great work man, A question could you please explain what is residual value how to decide which value is best how the equations achieve this value thanks..

Nice tutorial , I am really enjoying it . But please can you make a video on the flow that causes scour around a pile structure, and also a flow that of a tidal turbine . Thank you
Here you have mentioned there will be another tutorial on adjusting the number of CPU processors to be used while solving. Did you already make that? Great work, by the way.
very good tutorial I really needed someone to explain these stuff as I am like an old lady working on computers
Thank you. You can contact us anytime if you have any query.

Thank you. Please share.
how do we set the type of mesh ? either coarse or medium or fine
your tutorials really helped practicing models,Thankyou.
You are most welcome.
In this tutorial, when i am naming the upper boundary as axis and bottom boundary as pipe wall, why the calculation is giving zero point error?
You need to create the geometry like that, it means , if you want the top wall to be the axis you need to draw the rectangle in the 2nd quadrant, the axis line you want to create must be on the x or y axis.

Nice video! How can wall shear stress be generated in turbulent flow?
Is it possible to extract the G value of the graduated velocity from the Ansys program?
perfect!I was wondering if i can choose an axis that away from the boundry instead of the boundary itself
If do like that, you would get results for an annular pipe.
Thank you.

This tutorial will help you to put the parabolic velocity profile at inlet.
i still have not gotten a parabolic profile after following the video step by step
I still do not know what is wrong
In which video do you guys talk about importance of meshing?
Currently we have not much video on meshing. Will try to make such tutorial. As many viewers are also facing difficulties in meshing.
Why did you directly made 2d of circular pipe? like can we proceed by circular section?
Generally 2d geometry takes less computational effort. You can do it in 3D pipe section.
The class is saying it very well - understood way. Good tutorial. Thanks a lot.
Thank you for you comments, please like and share our videos.

The pipe outlet velocity is higher tha inlet velocity?
amazing can you please make a simple tutorial for two phase flow simulation in vertical pipe ansys fluent?

I'm not getting option of adaptive meshing in ansys 16
Adaptive meshing option is not available in older versions. Its available in latest versions like version 19 and above.
Here the exit velocity is increasing?
As the initial simulation provides results for only half the pipe? Do the results then need to be doubled or is this the results for full pipe but only shows half in the image?
Its for the full pipe. As you can see, there is an axis boundary condition provided in BC. Which informs the solver regarding the continuity of the pipe.

In the problem statement you have pipe, why you use rectangle shape?
It's the 2D axisymmetric geometry of the pipe.

Hi. Why did you select diameter 10 instead of 20
It's an axisymmetric geometry,, for that you need to select the half of the pipe.
great work man,

Residuals are the error value, that how much the iterations value differs from the previous one.
