Simulating fiber connections

Hey,

is it possible to connect 2 cubes with lines? The idea is that I have 2 cubes and I want to connect 2 facing sites with lines to simulate a fiber connection. After this I want to use the fibers tu test some loading conditions and test dhe behavior of this structure with a cycling loading approach. That indicates my next question which property is the best definition in Hypercrash to use the lines as fibers with a dfined diameter?

I uploaded my Hypermesh project.

Additinally i uploaded a picture of the idea. I want to create these lines as a kind of connectors between facing nodes. (Look at the picture)<?xml version="1.0" encoding="UTF-8"?>

Thank you very much.

Best

Max

Hi Max,

My suggestion based on your query is to model with beam elements. You can define the diameter for the beam cross section in HyperBeam menu.

You can get more details on this at: http://www.altairuniversity.com/modeling/meshing-2/1d-2/

Hi,

tahnks for your answer. I did it but now I have problems to import it in Hypercrash, because the cube in the middle is missing (attached files). Can you help me with it?

Hi Max,

Please try with the model attached along.

Hey,

thanks you. What did you change? You add a new cube? Because I also did it and I was not sure, if the connections are still defined, if I just add a additional cube.

Best,

Max

HI Max,

I just organized the truss elements in a separate collector. No other changes were made in the model

Hey,

thanks for your help.

Just a short last question. Is it possible to automate the construction of rods? Because I have to build i a big model and this would be tons of rods. I mean that you can do something like took some nodes and they look for their nearest neighbors and then connect it with the nearest node?

And also to model this rods with different cross sectional area liketapered beams? For example a bigger cross sectional area at the beginning, a smaller one in the middle and againg a bigger one at the end?
