How to create a retangular Facet

0 votes
asked May 31 by alanbds (140 points)

I'm new here, and I'm trying to create a retangular facet to simulate a dormant railway. I've only found the Fat-Facet at the exemples and couldn't change it to a retangular form with sharp corners. The fat-facet is a triangular form with round corners. Can I make this retangular form with DEM or do I need to use Finite elements to make this shape?


Thanks in advance,

Hi Alan,


I am not sure what dormant railway means. Anyway, use two facets to create quadrilateral shape, either by hand, or use perhaps use woo.triangulated.quadrilateral. If you also need some non-negligible thickness (and rounded quadrilateral -- from two partially overlapping fat facets -- is not good for you), use woo.triangulated.box.

If you provide more context for your need, I might be able to help you better.

Best, Vaclav

First of all, thank you for your attention.

I'm doing a project that uses a box of 6x8x6 meters, filled by rail ballast. And later a wooden rail sleeper is inserted, and a cyclic vertical tension is applied to this wooden sleeper.

I'm using the Clumps to simulate them. And after the cyclic tension I will check how to apply it.

However, my question is about the railway sleeper. I'm trying to create a rectangular piece to simulate the dormant, but I still can not.

If you have any tips or solution I will be very grateful.
