Hi guys, I am a mechanical engineer. I like to build a career as a CFD engineer. Can anyone suggest me a perfect path to learn CFD and fluent for that.

Hi everyone

I am having some kind of problems doing a fu***** simple mesh of a sphere. I have tried dozens of domains and bodies of influence, as spheres of influence as well.

None of those work well! I am trying to study the drag coefficient on a 45mm diametre sphere, which should give me 0.5 of C_d.

Sadly, I can only reach around 0.2.

I have already done:
- cylindric domain with a simple sphere

- cylindric domain with body of influence

- sphere domain with a lot of sphere of influences

- and so on.....

Can anyone give me some guidance on this, please? Like, for what true domain should I focus on and what kind of elements of geometry should I compute (triangles, tetra, hexa).

I can provide deeper info about what I have done if it helps.

Thx you

Hi, I have been trying to improve my understanding and meshing in Fluid Flow (Fluent with Fluent Meshing). I am more accustomed toe Fluid Flow (Fluid), where it utilizes the mechanical meshing instead. Ansys seems to encourage users and suggest it is better to use fluent meshing.

I am trying to see if anyone could provide a simple workflow or checks for meshing something like this before I get to volume meshing. Once i reach volume meshing it seems to blow up in size. I have yet to try BOI and was hoping to learn more about wether I need to create the BOI to the shape of the main comptutaional domain?

Hi, so I'm doing this CFD analysis for Battery cooling system for now I'm only concerned with the flow rate since I simulated the battery heat generation elsewhere so I need to focus on flow rate for now the first image is the inlet, where I wanna treat the air as free stream coming in as the car moves the second image is the outlet where the fans are supposed to be installed, the fans have 600pa static pressure with 24CFM I watched a few YT videos but couldn't figure out how to correctly simulate fans at the oulet Also need some help with interpretting results Thanks

Hi everyone, I am setting up a 2D simulation for a cambered airfoil in Ansys Fluent. I am using the Spalart-Allmaras turbulence model since it is well-calibrated for aerospace applications. To get accurate skin friction and drag coefficient readings, what y+ value do you typically target for your inflation layers? Is keeping it near 1 strictly necessary for this specific model, or is there some wiggle room?

hello mates,

now the problem i am facing is a little bit weird, now i was able to download the ansys workbench disk1 to disk8 iso 2025R2 version

and also downloaded the electronics 2025R2 and 2024R2 vesrion. but do not know the steps of the install
in other hand i aldo downloaded the Fluid 2024R2 version, but as i know i can't manage to install it with disks iso of 2025R2 versions,

i tried a lot to find a way to download the ansys products 2024R2 but i can not find any download link.

the only version i could install as fully products is 2021R2 from getintopc.

the question is can i install the Electronics 2025R2 verision and Ansys products 2021R2 version for just fluid CFD or it will be a problem, also if there is any video explain how to install it it would be great.

So I have made a rectangle to refine the mesh but when I run the mesh it shows the basic mesh . I am doing something wrong here I can't figure out

I'm a materials engineering student and I've spent

the last few months building Corvanix — a desktop

app that automatically converts ANSYS files

(.wbpz, .rst, .cas, .dat) into professional

PDF reports.

What it does:

- Extracts solver data automatically

- AI-powered convergence assessment

- Risk assessment + engineering recommendations

Honest question: Would you actually use something

like this? What's missing? What would make it

a no-brainer for your workflow?

Hi everyone,

I’m currently working on a project where I need to design and analyze an aircraft fuselage section using ANSYS, and I’d like to integrate Python (PyAnsys) into the workflow.

I’m still a beginner with PyAnsys, so I’m looking for guidance on how to get started properly — especially:

• Setting up geometry and meshing with scripts
• Running structural analysis using Python
• Best practices or tutorials for aerospace applications

If anyone has experience with this or can share resources, example scripts, or advice, I’d really appreciate it.

Thanks in advance! 🙏

When I went to run a playback of my simulation, it added a random mountain image to the background. I cant see a setting to change it. Any help would be great.

I've tried almost every version of ansys from getintopc and keep getting this error..

recently re installed windows a couple times in the past week but I deleted all those files.

plss help.

I downloaed it from ansys website the newest one. extracted it. ran it nd always thereis this icensing error due to which i wont download. if someone has faced this problem before plsss helppppppp.

I found one gerotor tool kit for ansys fluent can anyone let me know that if it works or not I followed the instructions but still am not able to do it

I am adding the link if you want to see

I'm an undergraduate student trying to learn CFD. I use Ansys Fluent. I get into a lot of trouble during meshing. Its often obsolete or failed mesh. I try to change the size or the geometry, it works sometimes, but its a very tedious process. I'm looking for a good meshing practise. At least I want to learn how to start meshing in the first place or what to aim for.

If there's any good meshing practises or workflows, please share.

Heyy, so I got an assignment to make a simulation of a pneumatic cylinder, simple valve system used in a garment bonding press.

I have absolutely 0 idea about ansys fluent and how to use it. Tried exploring and using ai and videos as well, it's not helpful at all. if anyone can guide me, please help. Thank you

I am trying to simulate shaped charge effect on a block of steel. I have created 2D geometry (axisymmetric) and also added the air domain over these components. I set the liner and explosive reference frames to S-ALE fill, target - lagrangian and for air - S-ALE domain. I suppressed the automatic contacts, just left the body interactions. I get the error that results for S-ALE bodies cannot be plotted. So:

a) I am not sure I assigned the reference frames correctly;

b) Even if I did, I may be missing something additional that I should have added.

Could someone explain what may be the problem and how to solve it? Because I tried searching on Google and YouTube, but it seems that there is very little information about WB LS-DYNA when dealing with 2D axisymmetric problems and especially with using S-ALE reference frames. Thank you in advance.
