What is difference between Constraining nodes(directly from analysis->constraints) vs. rbe3? I am trying to do tensile test using Ls-dyna solver. Please post your comments.
Hi,
thats are complete different things:
*constraints: is a boundary condition of type *BOUNDARY_SPC_NODE in LSDyna
*RBE3: is a element of type *CONSTRAINED_INTERPOLATION in LSDyna
*BOUNDARY_SPC_NODE is more or less equivalent to a SPC in Nastran / Radioss Bulk
*CONSTRAINED_INTERPOLATION is more or less a RBE3 element in Nastran / Radioss (but not the same)
Please refer LSDyna Manual for mor details.
Regards,
Mario
