Hi, I am working on my final project and I have some simulations of two concentric cylinders that I have done in 2D. These results are exported to CFD Post and I want to show them in 3D but as if it were cut by 2 planes forming a wedge.

I have managed to show the complete tube in 3D but not cut and I can't find the solution. (One of the images is how I have done the simulations in 2D and the other how it is in full 3D)


I don't know if I explained myself well, I hope someone knows the solution.
Thank you

I think what you want is this. In CFD-Post you can create two planes with the desired angle between them. Then you can plot the contours just on these two planes.


- Right-click User Locations and Plots -> Insert -> Location-> Plane.
- Choose the appropriate type. Maybe XY for the first one.

- Do the same with maybe point and normal for the second.

- Right-click User Locations and Contour

- Under Locations select the two planes you created above

If that is not what you mean, please reply and we can find another solution.

Hello this is Gulshan Negi
Well, visualizing simulations of two concentric cylinders cut by two planes forming a wedge shape in 3D can be achieved using visualization software that supports clipping or cutting planes. By importing your simulation results, creating clipping planes, applying them to your cylinders, and adjusting visualization settings, you can create a visual representation of the cut cylinders in 3D. Remember to consult the documentation or tutorials of your specific visualization software for detailed instructions on how to create the desired effect.
Thanks

Hi, thanks for your answer. I try what you told me but the problem is that since it is a 2d simulation, to view it in 3d I use the "Default transform" option, so if I define an XY plane it is shown as I show you below and it does not make the contour.

Sorry I misunderstood what you meant. Try this:


1. Under the default transformation turn off instancing info From Domain
2. Set Apply Rotation (and pick appropraite axis)
3. Under Instance Definition, uncheck full (I think this is what you did before). But now put a value of 7.5 degrees.
4. Then up above, input the number of Graphical Instances. For example 12 would be 90°, 6 would be 45°, etc.
