I have been trying to simulate the triaxial test on a UBC PLM sand sample with fibres reinforced into the model. The fibres are assigned as embedded beams. The sample is cylindrical with a diameter of 50mm and 100mm in height. The analysis works fine until the fibre count is less than 600.
The problem is when I imported the geometry of 4647 fibres in the model from the AutoCAD program and started the meshing, the program crashed.
It crashes just after clicking the mesh stage.
I am uploading the bug report, photos of the sample, and the fibre .dxf file I am using.

Hello Shashank,
That is indeed a very interesting test.
My first question would be if you have tried first with a few fibres rather than importing 4647 objects directly. Simplifying the model can help you get some results, but as Berk mentions, I am not sure how far it can go.
I would expect meshing issues and probably pushing the limits of our finite element meshing code to an application that was not really intended for.
