Hi Khizam,
I'm interested in any positive answers you receive, but I'll write a negative one in case there are none. This is a *very* difficult problem. It probably does not require any UDF or Scheme, so you are asking on the wrong forum, but even I know that this is a very difficult problem. Your first step should be a literature survey. Have you tried this? Can you point us to any related work that you would like to copy or improve on? If there is nothing even slightly similar, this should alert you to the idea that it could be a multi-year project. Good luck! Ed |
Thank you so much for ur guidance. Ok I have another question to u. I have a parabolic 2d surface at the centre of the domain. Can I move that surface down the domain during to gravity in fluent,if possible could u pls tell me how to do that.

Hi Khizam,
I'm guessing that you are just starting out at CFD and Fluent. It would be best if you could complete some basic tutorials on that, and then ask some specific questions on the appropriate forum if necessary. Best regards, Ed |
Yes I completed some tutorials. The problem was, in the console it is showing "updating dynamic meshing is failed.negative cell volume is detected." But the mesh didn't contain negative volume. But may be remeshing it may be negative. So I kindly tell me how to solve that.

Hi Mohamed Khizam,
As I have said, I think this is probably the wrong forum, and the thread name no longer matches the question. I suggest you start a new question in the general Fluent forum. It will help if you explain some basic details of how far you have got and what you are trying to achieve. I have a general observation: it is much easier to move air past a stationary obstacle in a model, rather than moving the obstacle through stationary air. The effect on drag should be the same. However, I do not intend to answer more questions in this thread. Good luck! Ed |
