Hello sir, it would be really a great help from your side if you could make video on the cfd analysis of a rocket with refined mesh. Your explanation is really appreciating, I am easily able to understand the cfd from your videos. Thank you sir.
at 4:30 (after using facing splitting and before generation) i am facing this problem: It says ANSYSWBU.exe encountered a problem. and shows A diagnostic file has been written : C:\\User\sai\App data\local\Temp\WBDumpfile.dmp and workbench closes suddenly. please help me for this problem
Hi sir, I have a unique problem I simulate a 2D axisymmetric steam ejector the flow is a very high speed, 1300m/s at the outlet of converging-diverging nozzle the case is a Density-based problem, with water vapor(density: ideal gas) as a working fluid my mesh is coarse (2000element) the simulation goes well but when my mesh is fine (40000-60000 element) the floating due to excessive temperature occur actually, my orthogonal quality, skewness, and aspect ratio is very good I don't really know what the problem is
I’m modelling an aerofoil using this mesh style, does the size impact the results of the cfd processor.what I mean by this is, my aerofoil is currently scaled down by some factor and thus so is the domain so will this size decrease affect the Ansys cfd results. (Lift and drag coefficient)
in recent ansys version say 19 and above , we dont see the options like advance size functions, proximity size functions, max face size etc. can you please explain the same meshing with the latest version of ansys. Thanks
I have been testing with 2D structured mesh and found that my lift and drag coefficient values differ according to different values of bias factor...so i am a bit confused how to find correct bias factor. I have tried bias factor formula provided by CFDnija but it didn't resolve my simulation at all...please give me any advice
Well, I'm sorry that you are receiving a late reply! But hope it helps someone else sailing in the same boat. The thing is, you should ideally estimate the flow Reynolds number over the surface, followed by an estimate of the scaled wall normal distance y+ based on the first spacing you have set near the wall. y+ is always
Thnx for your video . i got an error in launching the mesh into setup. it says (the surface body cannot be changed into fluids since they are different kinds).How can i resolve this.

I have been trying to do structured mesh for two weeks. I was losing my hope then I saw this video. Thank you!
After spending hours of time in vain, I came across this video and this was the BEST I have ever seen in generating structured mesh

how to do this in 3D?
Thanks. It's very helpful. Keep it up.
how can i create a structured mesh with boundary layer? inflation control and face meshing are not compatible.
Really nice. Please keep sharing nice videos on more complex meshing using ANSYS

please help me for this problem
Thank you for your videos! Helps a lot.
how we can do in 3d , actually splitting similar like that or we need to do different
Hey ! Did u find a solution for this ? I try to do the same for one project but it is not working ... :(
My god, this is a very good video!!! Thanks.
Hi sir, I have a unique problem

actually, my orthogonal quality, skewness, and aspect ratio is very good
I don't really know what the problem is
Your tutorial helped me a lot! Thank you.
It is clear, thank you very much
yep, this works. i am surprised the mapped mesh option is no longer available

Amazing!
Pretty Helpful! Many thanks!
Very helpful, thanks!
Sir can you please explain how to the above in 3D?
YES i need it too
GOOD work man keep it up
How to do structured mesh for 3D rectangular wing of NACA 0012 aerofoil? My fluid domain is of half elliptical shaped.
use icem cfd
PLEASE UPLOAD A SIMILAR METHOD FOR FLOW OVER CYLINDER
Is it possible to do this with two seperate airfoils in the same geometry?
in recent ansys version say 19 and above , we dont see the options like advance size functions, proximity size functions, max face size etc. can you please explain the same meshing with the latest version of ansys.
Thanks
I don't do this anymore.

Hi, I want to know how to model a simple superhydrophobic surface in Ansys workbench or icem cfd? Please share.
Excellent vid
I have unpinned my mesh tab what to do
Good job bro ..!! Thanks
Thnx for your video . i got an error in launching the mesh into setup. it says (the surface body cannot be changed into fluids since they are different kinds).How can i resolve this.
Change the type to 'Fluid' in the Geometry window
Good stuff!
please tell me how to select quad element because whenever i'm following the steps its giving me triangular mesh. Thank you
Quad is 3D only
It seems I can also get the meshing, without the "Lines from Sketches" step
Thank you for Meshing help can you tell me 3D meshing
Great video! How to mesh a rotating wind turbine rotor???
it's good. but I have trouble to do the same on my own computor
5:05 mesh sizing
i am unable to import solidworks model into workbench
SAI CHAITANYA DASARI K V save it in STP format and then try. you can also use iges format
please upload in HD so i can read the commands ( or screen record in HQ )
can i get the geomtry file
I need someone to help me to apply structural Mesh
Anyone who knows the ANSYS fluent well helps me
Thanks❤
I have other videos on this too
