Shells-Solids Elements Connection in FE Model
To recover the rotational DoF at solid element's nodes coincident with that ones from a plate/shell element I normally make use of RBE3 with a 456 on the dependent (coincident) node and 123 on three independent nodes chosen from the solid's nodes in the face "normal" to the solid-plate joint.- AIUK

NASTRAN Rigid Element in a Thermal Analysis
Hello everybody Trying to run a zero stress check on a complex FE model. Changed the CTE to the same value for all elements, applied a delta temperature and checked stress concentration (Von Mises). I've got problems around interface RBE3 so I changed their formulation from linear to Lagrangian...- AIUK

SPC Forces when running analysis with CGAP different then using RBE3
When I need to simulate contact in a LINEAR (SOL 101) analysis, I normally make use of linear gaps (combination of SUPORT cards and MPC elements) calling the CDITER parameter that make possible an iteration process inside a linear analysis. CGAP is a feature generally used in non-linear...
