Considering the element types available in CalculiX (no easy fasteners like in Abaqus, unfortunately), 2-node springs might be the best. They aren’t supported in PrePoMax yet but their definition in the .inp files is pretty simple so they could make sense for such connections.
In CalculiX there are three types of spring elements:
SPRING1 - between a node and a ground
SPRING2 - between two nodes, acting in a fixed, selected direction
SPRINGA - between two nodes, acting along the line joining the nodes
In the current version of PrePoMax there is a point spring and surface spring constraint available. Both use SPRING1 elements and thus can be utilized to apply springs between nodes/surfaces and ground. It would be nice to also have a support for the remaining two spri…
Hello! I hope you’re all doing fine.
Since I work mostly with riveted joints with dozens, hundreds if not thousands of rivets, usually setting up so many connections is very tedious. To improve this aspect and bring new functionalities to the software, I would like to suggest faster ways to connect many parts.
RBE connecting many geometric features: in this tool, the selected geometries would be connected together using a RBE. One can select adjacent edges that will be glued or welded togethe…
