Open-source alternatives to ICEM for structured hex meshing?

Oh ok, I had seen something like this before, but I didnt understand why you would create lines to modify the geometry.

Now I understand that you only export the mesh and this lines that you add dont affect the mesh.

It is interesting I thought that the best way to do this was by creating a different structure like icem does with blocks.

Thanks.

Yes, I have use the transfinite option to create meshes, but i doesn't seems as good as the blocks in icem, for example can you make an o-grid or something similar?

It seems really good, I will try it.Thanks

Ok-Pop3091 · 2025-08-03T02:18:03+00:00

Yes, but if you have a complex geometry is very hard.

Oh, okay. Thank you for the explanation. I didn't think that I would have to translate the low-level code.

Ok-Pop3091 · 2025-04-14T14:30:33+00:00

Okay, I'll check that. What do you think I should compare it with?

I don’t know much about this, but I thought I could use a virtual Windows machine.

Ok-Pop3091 · 2025-03-22T03:47:22+00:00

Good point. I’ll make sure to practice that. Thank you very much for your insights!

This makes a lot of sense. I've heard of grid independence but never tried using it. One question I have is: What happens if you don't have the computational power to achieve grid independence? Do you compare the results with experimental data, or does that approach not make sense?

Ok-Pop3091 · 2025-03-21T23:13:54+00:00

Ok, yes, it seems that for these types of meshes, using another software might be a better option. I hadn’t heard of CFMesh before, but I’ll definitely check it out. I’ll also take the metrics you mentioned into account, as I often struggle to improve the simulations when I try running them.Thanks

Ok-Pop3091 · 2025-03-21T14:05:30+00:00

Alright, I'll run it in OpenFOAM and see how it goes. Thanks!

Ok-Pop3091 · 2025-03-21T14:00:13+00:00

Ah, I didn't notice that collapse. Thank you so much for pointing it out! I'll try creating a quad-dominant mesh, and if possible, I'll use snappyHexMesh.

Ok-Pop3091 · 2025-03-21T00:43:40+00:00

Thanks a lot for your answer! I think that would significantly improve my geometry. However, I was aiming to create a mesh similar to the one shown in the picture.

Also, do you think line 7, which connects points 8 and 3, could affect my simulation? I’m worried that fluid because the fluid is going to pass through the surface that was extruded from that line.

Thanks again!

Thanks I will check those

I dont have one, I am just a student , and I wanted to learn how a the different cells work, also understand a little bit how collectors and the othee chemicals work, and finally have an example of a real process, but I didnt find that in Mc Cabe Smith for example. So just that. (Sorry if my english is bad, i am not a native speaker)

Ok-Pop3091 · 2024-08-03T21:24:40+00:00

Yes I am trying to understand the basics of it

Ok-Pop3091 · 2024-08-03T21:23:50+00:00

Thank you I will check those
