Barinternal Forces - PositionResult -FEM API- Grasshopper

[Arun_N_Dinesh]

Hi,

While extracting bar internal forces, I am facing some issues, which I have listed below. I would appreciate your help.

1. I would like to extract forces only at specific points along the beam, such as the end points and the mid-point. However, the PositionResult is currently showing results at many default locations along the beam. How can I modify or control these result positions so that forces are extracted only at the required points?

you have two different approaches.

1. you can create a result points on a bar and return results only for the result point
2. you can return the value when the position results is equal to the total length / 2.

Hi Marco,

Thank you for the input

1.Yes, I do understand I can create ResultPoint in FEM model and call those ResultPoints by changing the Valuelist of ResultOptions.

2.Instead of post processing the panel data of PositionResult , Is it possible to divide the Bars uniformly by using the Step input data of ResultOptions or control the Default internal division of bars in FEM model or in GH-API?

Have a look at the following link.

Set global configurations​ - LiveLink | FEM-Design API

There is a global value that will help you in divide the beam in a define number of elements.

Hi Marco,
Thanks for the link! Never explored. Useful for new users like me

Resultpoints option is working fine.

But even after changing the Global settings the ByStep option bar divsion is not reflecting in GH.

Maybe I’m missing something , Still I’ve a workaround by creating Resultpoints !
