Great tutorial!!, but I have a problem with the mesh, when trying to open it in Fluent, the mesh option is blocked and it is only possible to select the mesh and data, if I select this the program gives me an error. I don't know how to fix it PD: I have the free student version of Ansys
Hi, Your videos are awesome. I have a question. when defining the cell zone condition for the impeller, you entered the value of 1450 rpm (absolute) and when defining the boundary condition you typed the value of 1450 rpm (relative)for the impeller wall. As you entered the value of 1450 rpm two times, will the rpm of the impeller be higher than 1450 rpm?
Thanks for your VIDEO I have a question, During the initialization it said "convergence tolerance of 1.000000e-06 not reached during the hybrid initialization" what's wrong ? ...

May I ask you two question please when you input the boundary conditions rotational speed you put it relative to adjacent cell zone not absolute is that correct? second question can I take this tutorial as a guide in a case of centrifugal fan specially models, methods, controls..etc?
I am using Ansys 15. I don't find mass flow outlet in outflow section in boundary condition . How I can give mass flow outlet boundary condition. Please help me.
@@ansys_cfd I'm facing the same problem. I couldn't get what you mean by ''mass flow outlet in outflow''. Could you please explain more Sir? There is mass flow inlet but there is no mass flow outlet.
@@burakkaplan7827 Hi friend; the boundary conditions will change in the new ANSYS version, in your case put mass flow (inlet) and pressure (outlet). Regards
Nice work, thanks a lot. Is this a different approach to what Fluent's User Guide recommends? From what I understood from the User's Guide in MRF you should activate frame motion for both cell zones and leave 0 absolute rotational velocity for static cell zone. Also, parts adjacent to rotating cell zone should be left with 0 rotational velocity relative to adjacent cell zone. Did I read it all wrong or are both methods valid?
I cant get logical conclusion after the analysis.Pressure is going down at discharge.I dont know where I am doing something mistakenly.Can you help me?
Hi, Thank you for your great tutorials.. Ansys takes much time solving this, each iteration takes like 20 minutes, I think it will take me days to finish it this way.. How can I solve that? Can I reduce the number of iterations or something?
Hi friend; If you reduce the number of iterations the model probably does not converge, the best solution for a large number of mesh elements is to increase the number of processor cores. You should also check if your ram memory is loose. Best regards
Hi CFD NINJA , i have problem with my project , i was going to do a compressor surge using ansys simulation . was it ideal if i take rotating speed as parameter
when import this mesh file appears to me an error because i have student license and i can only use cases containing less than 512000 cells. you can help me? please
Hi friend. In this case it is necessary to have more than 500,000 mesh elements, simulating a pump with few elements would lead to erroneous results. Regards
@@ansys_cfd yes sir now it works thanks a lot appreciate it, I've tried before it was not working. NINJA I'VE mailed you a matter kindly look into it please. My email: xperson908@gmail.com
hey please i need your help can you please help me out ........actually i am rotating the impeller in wrong direction but how do i make it rotate anticlockwise .....i am getting negative pressure at the outlet due to this.....like the is no -Z direction option in the turbosetup.........please help
Hi friend, In this case I dont use inflation in the inlet and outlet zone but you can use it. If you skewness is high you try decrease the mesh size. Regards
Great video. I have to design a 2D francis turbine and I am trying to get an overall idea on pump/turbine modeling. Also, why the UI in your Fluent looks so neat? Is this on Mac? Thanks a lot.
@@ansys_cfd Actually, I'm a beginner, and I have a question: if we simulate the air in the pump, not the water, the fan and pump also need to use rotation fluid area? and in fact, we mesh the fluid which influenced by the fan, not the real fan, right?
I have a problem with my own project which is cetrifugal pump too.Cell zone consist of two parts including volute and impeller.Boundary Condition is the simirlar with your project.There is a litte difference when compared with yours. I dont know why but I predicted that I couldnt prepare my geometry for cfd analyis.Actually I am a new one for cfd analyis.After the analysis I have been obtaining really absurd conclusion.Pressure is minus at the end of the volute.I cant fix it.Can anybody help me?
dear ninja I want to introduce méthane instead of water in this pump I've done this but the solution is no more converging what other parameters must I change to have a convergence ?
dear ninja the methane (gaz) I want to work with is under his liquid form under -102° and 20 bar if you have a model of cryogenic centrifugal pump please that's the type that I want to work with
Ah ok, now yes, well I'm not sure if this design is suitable for the conditions of liquid methane, the pumps are designed according to the flow and pressure of operation. That may be one reason why it does not converge.
I think I have a bir problem for interface.Report deffinitons shows inlet total pressure is bigger than outlet total pressure.I did same for every steps.can you help me please.🙏🙏
CFD NINJA I am working on mine design.first I designed Vista CPD and bladegen then I created volute fluid cast and impeller fluid cast then meshed on mechanical I think I have problem with contacts.Help me please 🙏
@@melihcankayaaslan3826 Hi friend; If the impeller is larger than the internal edge of the volute, you need to subtract part of the domain in design modeler or the spaceclaim so that both solids connect to each other, both must have the same axis origin. Regards
Good question, is to represent what happens in reality. If we do not apply rotation it is as if the impeller were static and the water would only move around this fixed impeller.

Why did you set an angular velocity for the rotating parts ? In my opinion the should have a 0 velocity relative to the impeller zone
Hi friend; You can try it and after compare the results.
