The node model is not running

[[email protected]]

Dear stko operation team, good afternoon. I'm a beginner of stko. I've been writing TCL files before. Now it's very convenient to use stko.I built a node model based on experiments, and I wanted to get its hysteresis curve, but I couldn't run it in software. I checked for a long time but couldn't find the mistake. Could you please help me check it? thank。

Hi,

The reason that you got the error is that you didn't use BeamSectionProperty.
Then I changed your selection set for c-node (it was given an error that there is more than 1 vertex)
Now you need to correct your hysteretic material, the values can not be the same, but you can make them with minimal differences. Also, you need to check your Joint2D material (Mat C is not assigned).

Let us know if you have any trouble.

Best,
Valentina

THANK YOU!
Maybe you could tell me how to select the set for C-node.
I dont understant the meaning of it was given an error that there is more than 1 vertex

You are welcome.

If you try to add BeamSectionProperty to your old file by yourself and you try to run it, you will see this error.

The error tells you that in c_node selection set is more than one vertex. To solve it I deleted and created again the c_node selection set. Just this. I saw that it is one vertex now in your model, but something went wrong while you were modeling and you end up with two more geometries stored in your selection set that do not exist anymore. We will look into it, but the solution for you is to delete and create it again as I did. I hope I was more clear this time.

Best,
Valentina
