Interaction between solids

[ragopesa]

Dear STKO Team,

I hope this message finds you well.

My apologies, I hope you can guide with some issues related with connecting solids.

My goal is to model rigid bodies. In this case, I'm using different solids to "create one figure". Plase see the screen 1 attached. To join them, I'm using ASDEmbeddedNodeElement.

My issue is actually when the ntha anlysis is running. Only during few steps the body remains as one (Figure2). Then, it actually "disattached" (Figure 3). Could you please guide me to create the correct interaction to "join" the different solids.

I also attached my model

All the best,
Salvador

The way you defined the interaction for embedded constraint doesn't work.
You need at least:
1) interaction to the back solid: master = back solid, slave = all faces that connect to that back solid
2) interaction central vertical blocks to central horizontal blocks: master = all solids of central horizontal blocks, slaves = all faces of central vertical blocks that connect to those horizontal solid blocks
3) interaction central horizontal blocks to sides: master = solids of side blocks, slaves = faces of horizontal blocks that connect to the side faces

Thank you for your quick reply! It works!
