I am performing a steady-state thermal simulation my model consists of a composite having circular particles embedded inside a large circular domain. See the image attached. Now, I am importing a CAD model having those random small dispersed circles.
After this, in ansys, I am sketching the larger circular domain and then using surfaces from sketches I am generating the bigger circle.
Then I am using boolean operation to separate those small circles from the large circle as both of them have different properties.
But the problem is that at Higher area fractions of small circle the operation is showing this error ("Error: Operation would result in non-manifold bodies Context: Geometry Engine, while generating Feature Boolean1")
This is due to small distance between neighbouring particles(I have kept the min. distance as 0.005 mm). How can I troubleshoot this error as I am not able to identify the particle causing this as I have many composite of same area fraction but only some are causing this trouble.
If I am able to identify the close one causing problem may be I can reduce their diameter. Also How can I perform this in design modular reducing the diameter operation??
Dear Shubham Patil,
Have you ever considered using SpaceClaim instead of DesignModeler?
In SpaceClaim, you could create a section with all the particles and remove them from the matrix. Then, before moving to the meshing step, you will need to activate the "Share topology" option so that the features will have a conformal mesh.
Then, I would recommend you to generate your geometry with a Python script inside SpaceClaim too, so that you can parameterize the problem easily.
I hope it helps.
Cheers,
Ramiro
