Thank you for your comment. Yes, 1D Connections do support Selection Recipies. Some older versions did not around the time Universal Connections were first introduced.
There are a number of methods to model connections. Please see ruclips.net/p/PLRhczELP7wYLLIsQhnXbsS0NlGDSTmehm&si=gX3ppmOcGQmY5yt8 ruclips.net/video/cvTGMFbAjd4/видео.htmlsi=vzeI_QtGreK1nnBS Its up to the analyst to decide which method best reflects the real world. To do this, it is important to correlate your finite element model with a physical model to ensure your modeling practices are appropriate. Once you have confidence in your finite element modeling practices you can reduce/eliminate physical testing. We have a module in Simcenter 3D to help correlate modal analysis ruclips.net/video/NXSYQ9Mrn8I/видео.htmlsi=hPPb5cw_9y0D9fs2
I have a question regarding a structure that involves a sheet composed of two parts: a three-dimensional (3D) part and a two-dimensional (2D) part. I would like to join these two parts using a one-dimensional (1D) connection to perform Finite Element Method (FEM) calculations. A force is applied to the sheet at the end of the 2D part. After adding the 1D connection and conducting the calculations, the connection point behaves similarly to a door hinge. Could you please explain why this happens and how I can fix this issue?
Solid elements have only 3 (translational) degrees of freedom where shell elements have all 6 (translational and rotational). If the connection is along a line between the shells and the solids, it will act like a hinge. Instead of using 1d elements to make the connection, consider using edge to surface glue (in the sim - simulation objects). Edge to surface glue will create imaginary springs out to the width of the shell elements and prevent hinging. Another great place to ask these types of questions is on our community forum community.sw.siemens.com/s/ under Simcenter 3D.
For the spiders that connect to a selection recipe, the node numbers can be found by right clicking on the Selection Recipe and selecting solver syntax preview.
1D Connections do support Selection Recipies as far as I know and has done so for quite some time.

great video. However can they be use for fasteners ,bolts and spot/seam weld?which would accurately realize the real world effects of these?

Hi thanks for doing this
Is it possible to get the node numbers to which the spiders connects
For the spiders that connect to a selection recipe, the node numbers can be found by right clicking on the Selection Recipe and selecting solver syntax preview.
@@Simcenter3DTipsandTricks is there a way to find node numbers of a Boundary condition, thanks
