Actually, it depends on the complexity level of the geometry and the type of mesh you want to create, and also the accuracy of the numerical results.

Pls send me the details to infinitycfd@gmail.com to give you a better view.

Hi there. It will be done.

Hello, please send me your geometry.

​@@infinitycfd32Where can I send to you the geometry?

Hi, I sent the geometry on the infinite cfd gmail address that is on your channel

That's a good question and must be asked from someone who has worked with both software. But with respect to capability, I believe that ICEM gives you whatever you want for mesh creation, although it could be more intelligent in unstructured mesh type. Besides, it can be coupled with other Ansys software to make a numerical simulation easier. But, I don't have the slightest idea about ANSA. We can discuss more if you have any information about ANSA.

Please send me your geometry to infinitycfd@gmail. com, so I'm gonna give you a better view.

The outer layer of mesh is O-shaped. Actually, it enables the mesh to be perpendicular to the outer curve of the geometry and also improves the quality of the mesh in the peripheral curve. This mesh is an example of a quarter O-Grid. Additionally, H-Grid in the center of the mesh will be inevitable.

Thank you too!

I really appreciate your motivating comment. :)

Hi. thank you so much for your comment. Please, send me the images of your geometry to infinitycfd@gmail.com, so I can give you a better view.

سلام داداش مشخصه؟

Thanks a lot and it'll give me more motivation. Sure, I'm going to do it if time permits.

​@@infinitycfd32i've followed your channel and also activated the bell to be notified of you new videos. Do you think in this case is it possible to mesh the tube matrix with the "mirror" feature of ICEM?

Thank you so much Larissa for your supports. It'll push me forward to create more videos. Absolutely yes, because not only the geometry is symmetrical, but also the final solution and the behavior of the fluid flow and heat transfer are symmetrical. Consequently, you can run your numerical simulation even with the half of the computational domain. But you must notice, because there is a subtle point in this situation. The behavior of the fluid flow must be symmetrical. For example if vortex shedding occurs around the tubes you can't use the half part and you have to consider the whole geometry. If you want to create mesh for the whole geometry, you can mirror the blocking, but you have to associate the new faces of the blocks to the surfaces, so it's better to create the mesh for the half geometry and mirror the final mesh. If you have any further questions, please let me know.

@infinitycfd32 The second case is what I was wondering about indeed. In my case, unfortunately, I have no symmetry plane . I have a 'square bundle' of very thin tubes. I am thinking about meshing only one region of this square bundle containing only one of these thin tubes. I would do the blocking and pre mesh for this area only, and then convert to the unstructured mesh. After that, I would mirror the mesh both in x and y directions, drawing the whole bundle, which is a 20x20. But your last comment made me worry about the face to surface assignment because in the first "original block," the lines, points, and curves would be assigned to the block edged. However, I think I would have to assign the mesh surfaces to the geometry faces manually for the whole domain, and that would be unpracticle.

Actually, if you do the mesh transformation, there is no need to do any further works, because the surface and volume mesh elements will remain in the original parts after the mesh transformation. I mean the boundary conditions will remain intact. So, you create the blocks, associate the vertices, edges, and faces of the blocks, convert to unstructured mesh, mirror your mesh or any other transformation operation and it'll be OK and no further assignments will be needed.

Glad to hear and it'll give me motivation for creating more videos.

It's very kind of you and good recommendation. Actually, it's getting better in the next videos.

Hello, if you use two separate solid mesh for volumes with two different names there must be two surface meshes between them. Actually, they are coincident and one has the main name and the other has shadow suffix.

It's gonna be great to comment in English!

As you know Ansys ICEM capability is to create different types of mesh, especially structured types. And it doesn't have strong tools for geometry creation. So I recommend you use Solidworks and Autocad that have particular modules for creating helical pipes. And then import them into Ansys ICEM. If you insist on using Ansys ICEM for your purpose, what you need is just the circular cross section curve and also its central curve. At first you must create the points of central curve in x y z format. Then import them into Ansys ICEM to make the central curve. After that draw the circle of its cross section and drive it along the central cuve. You can do this in the Create/ Modify surface tab and the Curve Driven option.

Ok I know thank you very much

You create the geometry from solidworks or design model or spceclaim or autocade

I want to know which software did you use to create the geometry😂😂😂

Far as I remember I didn't create its geomtry. I mean I was given it. But in my view Solidworks will be the best option. ☺☺☺.

I have a couple of doubts ... Can you please help me with them 1) The DPM file shows different diameters.. I am using a Rosin Rammler deposition with variable diameter from 2-20 microns however when I extract the DOM file as per Reports> Discrete phase> Sample. I get only one particle size shown. 2) I am particularly interested in the number of particles that are trapped in different ranges (say 2-5microns, 6-15 microns , 16-20 microns etc).. but the number of particles that are trapped is not shown in this DOM file. Can you please help me with these Thanks

You're welcome.

About the first question this problem is originated by two possible issue: 1- Different diameters are not generated by your R-R distribution function or 2- You may not capture the whole injected particles. For example you do not select all injection if there is multiple injections. You should check it out step by step to find out the problem. About the latter question I should say that you can open the DPM file using Notepad++ and see the number of all particles. For the second part of your question, there is a facility in Microsoft Excel to get the number of particles in each diameter bin. By this means you can determine the desired diameter bins for example 1-5 micron and it tells you how many particles exist in this range. It is located on the Data tab, in the Analysis group, Data Analysis, and the Histogram.

Hi. Thank you so much, it's your kindness. This problem arises due to incomplete copy process. I mean the interior boundary is not formed correctly. May be it is from the value of distance for copying that should be precise and be the exact value. Or it may be from the incomplete merging operation for mesh elements at this internal boundary. Check it out and see your boundaries one by one to ensure that one boundary has not two surface meshes in Ansys ICEM CFD. You can check this possible problem by checking the number of mesh elements that should exist in one boundary. For example if the number of elements for a boundary is twice the value it should be, the two surface meshes must overlap and you have to remove it before exporting the mesh.

​@@infinitycfd32 Thank your answer, but I meet another problem that the replicated mesh could not display after it imported FLUENT, FLUENT only display my source mesh. I don't how to do.😣

Your welcome. Did you enable the volume mesh in Display tree before transformation operation? If you did check the number of just hexahedral elements before and after transformation in the Material point.

@@infinitycfd32 ohh，i solve the problem ，thank you very much .Looking forward to more of your videos!!!

Thanks a lot and good luck with your simulation.

In a simple manner Dear. You can create structured mesh for your geometry. You can see this video "Creating structured mesh for a wedge with the L-Grid method using Ansys ICEM-CFD." So at first you create an overall block for your cubic domain and then split it into smaller blocks in such a way to capture protrusions.

Thank you so much.

You can and try and try more and more. It's just a matter of time and you will be successful finally.

It's your kindness and thank you so much. About your first question: Trap boundary condition means that as soon as a particle impacts a wall, it is removed from the computational domain and has no effects anymore. As a result, Ansys Fluent can list all properties of this particle such as xyz coordinates, velocity, temperature, time, and so on, in a *.dpm file. You can obtain this file in this path: Reports> Discrete phase> Sample. By choosing the desired walls and injection(s) and finally clicking the compute button. And this the Tecplot template for visualization. drive.google.com/file/d/1OzIbYucFBeuozfeNv_hG5jbiVdPSVTA2/view?usp=sharing

@@infinitycfd32 Thanks so much for your response , my problem solved thanks to you🙏🏻👍🏻

I'm really glad to hear this and be successful with your research.

@@infinitycfd32 thanks,you too, keep up your great work👍🏻😊

Thanks a lot for your motivational words.

البته دکتر جان. I mentioned it.

You can see this video. It has a voice as well as is in the field of biomechanics. How to demonstrate deposited particles in Tecplot (Particle visualization in Tecplot).

Thank you! Cheers!

Ansys ICEM Documentation has four manuals: 1- ANSYS ICEM CFD Help Manual describes all the menu and options. 2- ANSYS ICEM CFD User's Manual contains theoretical information. 3- ICEM CFD Tutorials generate mesh for some geometries. 4- ANSYS ICEM CFD Programmer's Guide contains full descriptions of the text commands and usually is used for automation purposes. The best reference for starting is its Help Manual, but it is not necessary to read all of its content. After you get familiar with its main menu, you can go to Tutorial and learn its application practically. The Help Manual is available in Ansys Help and here is the link for ICEM Tutorial: engineering.purdue.edu/~scalo/menu/teaching/me608/tutorial.pdf As well as I'm preparing an ICEM CFD course for both structured and unstructured mesh generation and as soon as it's prepared I inform in my channel. It starts from basic concepts and leads to mesh generation for complex geometries. If there is any question, please leave me a comment or send me an email to infinitycfd@gmail.com.

Thank you

Your grace and be well everywhere you are.

It can be done by using the Create Midline option under the geometry tab and Create/Modify Curve options. The point is that it must exist two curves on your desired surfaces.

You can see this video for better understanding: Using extrude technique to create mesh for a simple cube in Ansys ICEM-CFD with this link: th-cam.com/video/J0HQNHQNLQc/w-d-xo.html.

Excuse me for the response time. This link contains the geometry file in *.tin format: drive.google.com/file/d/14n4FP_Cm4yTMsGhRLsF-bafjg98XLUut/view?usp=sharing.

@@infinitycfd32 true legend you are thanks most selfish here thanks

Thank you so much. In your case the procedure is similar to this video except you have to consider the pitch length of the geometry. For details I should see the geometry. Please email the geometry to infinitycfd@gmail.com to see.

@@infinitycfd32 Thank you so much for your response. The geometry with details has been sent to your email.
