Thank you so much Please forgive me, I confused. I dont know what should I do. please write again step by step. when I export mesh to fluent, surface of middle cylinder define as wall automatically. what should I do, now? Best Reagards Reza

thanks so much far, I am waiting for you:D

reza, in boundary conditions, you have to select the middle cilinder and put as a interface, you will have six interfaces, three from the tank volume and other three form the impeller volume. After in fluent you will have to connect the interfaces, the up faces, the down faces and the cilinder.

Thanks in advance

Hi Far, don´t worry but I would like to know if you really are going to send me the video. I can wait, but I want to know sure that you are going to send me.

Yes it has been on my list for long time. I hope to complete this week.

Hi Far:

I still waiting for the video, I hope you don't forget. It will be fine if you sent me the video before wednesday if is possible.
Do you need my email? or is possible to post here the video??

Thank you

Hi far:

Could you tell me If you are going to send me the video tutorial how to mesh in Icem the mixing tank? I would apreciate so much, I need it as soon as possible please.

Hello Far,

I'm trying to mesh up a stirred tank, but not with Gambit or ICEM, but with Ansys Meshing, and I have some problems. For the first question, is it a good option Ansys Meshing, or it's better if I work with ICEM? and then, as I see in your last comment on this post you said that you're making a tutorial on this, is it right? and can I have its link, or could you email it to me please?

Thanks in advance,
Solmaz.

Hello Far,

I also work on stirred tanks, and firstly I meshed it in Ansys Meshing, but no good results. I wonder if you had made the tutorial you talked about in your last reply to this post? I will be more thab grateful if you could share it with me.

Thanks in advance,
Solmaz.

no, I did not complete it. But i am thinking to do it now

Hi Far,

Thank you for answering me. So I'll wait for it!

So would you please answer one more (general) question? I tried a Fluent case with a mesh I made in Ansys Meshing by MRF method, which had swept mesh in whole volume except in rotating zone (arround impellers) in which the mesh was unstructured (actually as it was advised by a tutorial in Ansys Meshing), but the answers was not good at all, actually it did not converge!

So after some research in internet I reallized that it's better if we can use sweep meshes everywhere, even in the rotating zone (am I right?). So here is my problem in fact. I don't know how to create structured mesh arround the impellers, because Ansys Meshing says this body is not sweepable. Should I make it with ICEM? I mean is it the only way for that? in Ansys Meshing it's not possible?
And if yes, how I can learn ICEM? are the tutorials enough? because as I checked them, I don't see any simillar thing to this case (stirred tank I mean).

I will be really apreciated if you could guide me, I really need it.

Thanks,
solmaz.

ICEM meshing
 

Hi

I am working with gas-liquid stirred vessel. At first I made my mesh in Ansys but I did not obtain good results. I am thinking to make my mesh using ICEM. I would really appreciate if anybody can help me and explain me how I should work with ICEM in details.

Thanks
:)

Nasim,

Can you talk about your system a bit? How many impellers? What gas flow rates? Also by not getting good results could you elaborate on what you mean by that? What parameters are you looking at? It is well documented in literature that there are certain scenarios where gas liquid mixing system fall off in accuracy.
