Bubble modelling to simulate shape oscillations
Hello,
I'm trying to simulate a single bubble shape oscillation and I needed help in modelling it. I created the grid using Gambit. The problem I'm facing is that the bubble interface is not being exported. I have a made a square domain. At the center of the domain I've created a edge who's shape is that of the bubble. I meshed the whole square domain and then tried to split the mesh along the bubble interface. I'm getting some errors saying that the split is unsuccessful. When I tried by creating two faces but meshed only the square domain, the bubble interface doesn't get exported because the other face is not meshed. I do not want to define two separate faces which are non-intersecting and mesh them, as that will not result in a structured mesh. What I need is that the whole domain must be meshed as shown in the attached figure http://imgur.com/0lFY5jD. Then split the mesh along the bubble boundary so that it allows me to specify two different zones. Please Help! :( |
I'm fine if the grid is generated in any other software (Hypermesh or Pointwise or ICEM). At the end of the day, I just need Fluent to identify the two zones explicitly alongwith the bubble interface. Also note that the initial shape of the bubble is complex (not a conic).
For reference I again attach the geometry and grid I'm trying for. http://imgur.com/0lFY5jD I sincerely request for help, as I'm stuck at this problem since a week. :( |
We need the .stl or .tin file of your geometry to help you.
|
Since its a 2D problem I had prepared the geometry using Autocad. Will .dwg or .dxf format suffice?
|
I see that we can import .dwg files in ICEM. Here is the link for my geometry. http://www.sharecad.org/CADView.aspx...3-7d0c1b40c205
Here you go. The tin file, I've shared it. http://sdrv.ms/WfwFB0 |

Yeah did that. Please refer to the following link http://www.cfd-online.com/Forums/ans...tml#post405105
