Dear All, I am handling a problem about a air-liquid two phases flow simulation. I want to generate an animation about the water movement that influenced by the air.But I found that none of the display type in the animation sequence panel is suitable to define this animation. Is there anyone can tell me how to define this animate? Another question, does Fluent can display the wall or surface in semi-transparent color, just like the CFX postprocessor. Many Thanks! Jason

Jason,

The 3D visualization for multiphase flow is a challenge in FLUENT. One suggestion that might work for you is to create an iso-surface at the interface (volume fraction = 0.5). Then display that surface using grid display. You can also create an iso clip to display a range of iso-values but if the domain is large displaying may take a long time. You can try out some combinations.

Fluent can change transparency. Go to display --> scenes. You can also uncheck the "outer faces" box in this menu. I find this better than changing transparency due to graphics rendering. Hope this helps

Dear Pavan, Thanks for you so kindly to answer my question.It really provide a great help to me. I want to creat an animation to see how the water splash up under the impact of the air flow.In the Animation Sequence panel, I can only find the different display type below(the Grid, Contours, Pathlines, Particle Tracks, Vectors, XY Plot, and Monitor). How can I use the ISO clip to creat an animation sequence in an unsteady simulation. Can you provide me with some detail information about that? Many thank! Jason

Jason,

You have to go to surface-->iso-surf and create the iso surf with Vol frac = 0.5. Then when you define your animation display grid and choose the iso-surf you just created. At each time step it will display the corresponding iso-surf. The only problem however is that you may not be able to change the transparency of your other surfaces if you do it this way. Maybe you can do it in some way. You will have to try a few things for that. Hope this helps.

Dear Pavan, Many Thanks! Jason
