Hello there,
I try to model a bridge in ROBOT. I did some bridges before but never totaly in FEM. I have some difficulty to make my model right.
[1] I want to cut off a part of an panel whereby the cutting line is the cilindrical tube, see pdf. tips to cut these panels are welcome!
[2] is it normal that the material properties of the panels are not been shown?
Attached my model so far.

Model has no panels ,no bars . Only a few nodes and some lines.
Also ,no pdf.

Hello,
Thanks Rafacascudo for looking to my model. I think i put the wrong model to my post.
In the meantime i found the solution to make my model right. See pictures:
Hereby the section that i want to cut. i did this with command object commbinations:
I also attached my model so someone else can learn from it.
Congrats ! Very nice model!!
Do you really need the tubular sections of the protection railway to be modelled as panels( cylinders)??
Talking about that ,there are 4 assigned with different thickness compared to the rest of them

Hello Stefano,
Thanks the you took some time to look at my model.
With this bridge project I wanted to explore the posibilities within ROBOT to use FEM and compare this with another programme.
For the behavior of the bridge i also made a simple 2D beam model to check the results.
You are right with the FEM results about the accuracy. In some points there are large peak stresses. This probably is the result of elements that are not connected well.
When I had was anough time I would make a model with bars in ROBOT. Maybe I will soon, when I do this I shall post the results.
Cheers,
