@@VivekSaxena-df3bx Hi Vivek. Sorry, I don't check this email often. Anyhow I have seen your email now. Hopefully I'll check on coming weekend. For the time being I am away from my computer :)

@@WaqasLearnTech No worries. Thanks again for your consideration and reply. I will wait for your suggestions on the problem.

You can use (.prof) file to import your spatially varying field (such as velocity). You can import you file as File > Read > Profile The format of the file you can find in Ansys help. Do let me know if you can't find that

@@WaqasLearnTech Please share the link for the format. Fluent is crashing when I load the profile file.

For geometry transfer from SpaceClaim to meshing you don't need to do anything Just close the SpaceClaim and open the Meshing module from project schematic. The geometry will automatically transfer from SpaceClaim to meshing. PS: It is not true if you are using SpaceClaim as stand alone

@@WaqasLearnTech It still does not work. When I open the meshing module by right clicking and click 'edit', it shows me errors. I am using 2024 R1 student edition. In the workbench at the beginning, there are three options to begin the exercise, like Fluid Flow (CFX), Fluid Flow (fluent with fluent mesh) and Fluid Flow (fluent). I chose the second one.

@@RamamohanRVFirst option is for CFX. I am not using it The 2nd and 3rd options both use fluent for simulation but 2nd options uses Fluent environment for meshing. The third option uses Ansys meshing module. This tutorial is for third option Fluid flow (fluent). Try with that. When you will close SpaceClaim you would see a "green tick" on the the right side of geometry tab. It indicates that this tab is updated and you can open the next tab. In second option Fluid flow (fluent with meshing), the geometry doesn't transfer automatically to next. You have to import the geometry after opening the meshing tab. You can see that in this video kzbin.info/www/bejne/ravaeJR4mN2grMU However, I didn't show how you can use parametric analysis using 2nd option. Maybe I'll do in my next video

@@WaqasLearnTech Yes, this worked. Thanks a lot. I actually want to do this mesh sensitivity analysis for a 3D model. Whether there is a separate video from you ? Any difference from 2D analysis shown in this video ?

@@RamamohanRV I don't have any video for 3D case. But there is no difference at all. You can select the mesh controlling parameter in the same way as for 2D. It will work exactly in the same way for 3D.

Glad that it is helpful

Glad that it is helpful for you

To convert to .ttab file you don't need any converter. you can do it as follows: Open file explorer go to "view" tab. in "show/hide" group of view tab, check "File name extensions" Now you would be able to see the extensions of all file. Create simple text file e.g my_file.txt. This ".txt" extension will be shown automatically as you have checked the "File name extensions" Now you can simple change the file extension from ".txt" to ".ttab" Hopefully it will be clear now.

@@WaqasLearnTech thank you very much!

@@ndarualfian1539 no you don't need to assign time profile. Time would progress as per your time step settings (calculation tab). Your time step is not required to match the time profile. Fluent will interpolate if time step doesn't match with time profile.

I am glad it is helpful to you

Yes, you will have to create multiple bodies/Parts. It will be easier in 2D to generate the mesh as in this example. Your workflow could be like this Don't use share-topolgy, instead use imprint for (17:00 onward in the video) For the side zones where you want to have hexa mesh, define same number of division on the opposite sides of the body. Central part you can use insert ==> method ==> tetra mesh For 3D you use multizone method o´for the side parts to generate the hexa mesh. In both case don't use share topology

@@WaqasLearnTech my research is in 3D unfortunately, therefore it has to be a 3d domain. I already try to use the share topology with 3 distinct bodies, and its seem fine, two hexa is created on the sides and tetra in the middle by applying tetra mesh method on the middle body. why did you suggest not to use share topology?

Actually when you add boundary layers, hexa mesh get converted in tetra mesh in case of share topology. If there are no boundary layers you can proceed as you have already got hexa and tetra mesh as per your requirement. I would suggest you to use fluent meshing if you have boundary layers. In fluent meshing you can use share topology

Hello! Sorry to bother once more. I created a non conformal mesh. Do I have to create mesh interface where two non conformal mesh meet? I notice fluent create mesh interface automatically when I load the mesh file into fluent.

If you define interface/contacts in Ansys meshing, then you don't need to do anything in fluent. Fluent will read the interface defined in Ansys meshing Alternatively, you have to create the interface in fluent

I appreciate your suggestion. However, it won't be possible for me to do tutorial on endight as I don't have much expertise in it.

I will definitely do some videos on common errors and problems faced in thermal simulation. I already have recorded a couple of videos on meshing problems. I'll upload after editing. Meanwhile you can check on tge channel page. I have some advanced tutorials on general topics which are equally helpful in thermal simulations.

Hello Vivek, I am glad that these videos are helpful for you to proceed further in your PhD reasearcg. I just saw your email. Soon, I'll reply to your email as well. I would be happy to stay in contact with you.

I am glad that the this content is helpful for you. I am working on more advance tutorials. Meanwhile, if you have any specific topic, I would be happy to include that as well.

Thanks

It can happens if your target is confined inside your cutting body. To familiarise with the tool, try to use it by changing the order of bodies.

Yes, we can use it for 3D model as well. When you create a parametric geometry, test your model in SpaceClaim by at extreme value of your parameter. In general when you test your model, none of two faces should merge with each other.

I'm facing issues in assigning parameters in the 3d model, shell mesh and volume mesh generation If possible can you make a similar video for a simple 3d model?

@@jatinbadkar7951 I can make a video on that. It might take some time. Anyway, geometric parameterization is handled in CAD mostly (SpaceClaim). If you like, I can check your model.

I used SpaceClaim to create the model. For contact I use share topology in SpaceClaim. With share topology you can get the conformal mesh and don't need to bother about contact in meshing or Fluent. However, share topology is always not feasibible when you have a complex geometry. In that case, one has to define contacts in meshing and need to define as coupled in Fluent I have plan to make a complete video including model, meshing, simulation and post-processing. I'll discuss these scenarios in that video.

You are welcome. I am glad that it is helpful.

you are welcome. Glad that it was helpful

Thank you. I am glad that it was helpful.

Unfortunately, I am not expert in turbines. If you know the expression, then, I can help you to extract the information from simulation data.
