To Harry123456 and apd20,
I am very interested in this topic, would you please send me a copy of your paper to dauthanhvan@gmail.com. Or would you please tell me the name of your paper, so that I can look up at the library.
Thanks so much.

The simulation is modeled based on the prototype that I made. I also did the timestep smaller than the value you recommended. Thanks pja. Also, I assumed the maximum the value of the flow, and set the time step and mesh size so as to the flow will not skip any mesh size at every time step. I was...
Thanks pja,
Sorry that I havent made my question clear. My problem is that the unreasonable results. This is the results of the pump 100HZ create much larger output than the pump 7000Hz. Though the solution all are convergent.
Would you give some more advice?
Hi Drej,
Thanks for your sharing. Recently, I usually apply the tablular boundary condition by using Function Editor. It's is very easy to use and mentioned in the Ansys help. After building the function, use the Ansys Main Menu/Session Editor to copy the code of the function. It's look the...
Hello Kathik,
I found the solution several days ago, sorry to keep bothering you with this topic.
I want to model the solid heat source inside the fluid region, so that the heat flux is my idea.
The problem is that I forgot to apply the no-slip condition on the walls of the heat source, so...
Hello,
Could you please tell me why I can not apply the heat flux on the external areas of 3D fluid model (element 142).
Ansys can not understand the heat flux in this case, so whenever I hit the solve command, there is warning that the heat flux was applied on invalid boundary area type.
My...
Hello everybody,
Would you please tell me some ideas about Function/Table BCs in ANSYS. How to define a Function by using Command lines.
For example:
! Begin of equation: a*sin(omega*{TIME})
%_FNCNAME%(0,0,1)= 0.0, -999
%_FNCNAME%(2,0,1)= 0.0
%_FNCNAME%(3,0,1)= %_FNC_C1(1)%
%_FNCNAME%(4,0,1)=...
Hello everybody,
I am doing the FSI analysis in 3D model. In my model, the solid boundary will move with a particular freqency and amplitude, when this boundary moves it causes the boundary of the fluid change, so that we have something like a pump.
At the frequence f=100Hz, I got a nice...
Hi mohr,
I am sorry, I have no idea how to check the capatibility between Ansys and my video board, please show me how to check it. But what do you think about 2D case since it did very well.
Regard
Dear everybody,
I am working with 3D flow simulation, however, after I finish the simulation, I can not draw the particle flow as I want. Ansys launch this, but nothing happen with my model but a dark frame. I have done this with 2D problem and the flow particle worked very well, but in 3D I am...
Hello,
I am trying to find how to export the result from ANSYS into text file. For example, if I issue the EWRITE, or NWRITE, ANSYS will export the element, or node, information into text file without any comments. But when I use the element for export the element table, ANSYS always include...
Thanks,
This is the code I am metioning. I change the number of division into 70 and having problem. You can check it first with number of division about 7 (the right solution- saying ANSYS Inc.)

Hi mano,
I am still not sure about how fine the mesh is enough. If you have a glance throunh ANSYS document, you can see people want to use as least elements as possible. This is not reliable in some problem, esp. in fluid mechanic. And also in most of case I have test, I can not find what is...
Hi strain,
Tell me how to send you the model (by command text file).
At first, I also thought like you, and also doubted about the aspect ratio. So I made the other model in which the aspec ration is 1 (element type 145, width=depth=length). I maintain this aspec ratio while increasing the...
