    Solid to solid interaction not working

    Thanks for the input Mustaine. But why is CPRESS=0 everywhere there?. I thought on the deformation scale factor. But in every other contact region I've CPRESS not equal to 0, and when I increase the deformation scale a bit, I don't see interference anywhere but there. As I'm writing this I'm...

    Solid to solid interaction not working

    Attached is the input file. This thing is out of curiosity, it's not the first time that this has happened to me. I know there's a tie constraint there, but the vertical pipe is partitioned in coincidence with the weld, and the tie is in that region. The Surface to surface - "Hard"...

    Solid to solid interaction not working

    Dear colleagues, I'm having a little problem here concerning contact between two solids. I've modeled each part separately and then assembled them, I've defined and assigned boundary conditions, materials, meshes, constraints interactions, loads. I've submitted the job, and everything seems to...

    Beam & Shell tie

    Hello! I'm in need of some thoughts about this problem, which seems pretty simple, but yet I'm unable to resolve.. I would like to model a tubular space frame structure, (In the attached picture, the model on the left would be just a small part of it..) To reduce computation times I was...

    Boundary Conditions in tubular space frame structure

    My mistake.. I thought drawing the big picture would deviate the attention or disencourage possible answers .. The structure will serve as a building's slab. It's something like this: But instead of the trusses, we have something like this: I don't know the english name of this type of...

    Boundary Conditions in tubular space frame structure

    Hi, I'm still pretty new to Abaqus. I'm having some trouble with the boundary conditions when modelling the following structure: Model of an isolated node: Complete structure: I need to know the tensional state in the plate. I managed to get the model running and the analysis completed...

    Free Body cut in shell - Conceptual advice required - Abaqus 6.14

    Thanks corus! When you say that in that way I'll be able to see the stresses or forces along that line, you mean that I'll be able to select the nodes over that line and see/plot the stresses/forces? This week I started to use more partitions and I think I'm getting them. (At least I'm able to...

    Free Body cut in shell - Conceptual advice required - Abaqus 6.14

    Hi! My name is Matias, this is my first post here,, I need some assistance concerning free body cuts in Abaqus 6.14. I did a thorough search through the web and the documentation, but I just keep finding the same indications, and my problem is more "conceptual". When the model is a solid, like...
