Yes I try with your method mesh deformation.
With defined displacement of mesh I turned on solid motion (velocity of walek) and nothing happened. Walek doesnt move. Only interface move. Are there (ansys help) any examples or tutorials with solid motion ? Best regards |
I have never used solid motion so I cannot say. If none of the CFX tutorials with the software or on the ANSYS Community website do not show it then ask ANSYS support for an example.

So there are not any solution to make heat transfer on moving solid ??

So on the attachment I'm sending full visualisation of the problem.
So there other way to make solution of this problem?? I need to detrmine mass flow on inlets to make cool down moving pipes from 1100 C to 50 C. Best regards |
I would not do this using CFD. For a quick approximation you can use standard heat transfer and radiation coefficients and the properties of the bar material to get the cool down rate. That will give you a reasonable approximation.

In which module of Ansys I can do this ?
Best regards |
:) No need to buy software. You might need to buy a textbook to get the heat transfer coefficients though. The calculation can be done by pen and paper if you are keen, or write a simple solver in excel, matlab, python or whatever your flavour is.

Hello Glenn \\,
So I m working with this simulation. I'm moving fluid domain along steel pipe with second domain inside. So simulation goes on 15 steps and crashes with neg_vol error or ncwdist. What is the reason about these errors ?? In mesh displacement I have too much high exp.factor . can be this cause (exp.factor)?? In the first step value of the exp factor is 40 and increase each step to value about 99 in 15 step. Best regards |

So I have new idea for this problem
I define solid motion ( in the simulation this solid doesnt move ) but for this option i add boundary advection. So i have a question How to model continuous pipe from one side in Ansys CFX?? Best regards |
