I have created two solid bodies with a gap between them and meshed it with HEX elements. I want to connect nodes on adjacent sides of the gap using MPC (RBAR or rigid). SOL 101 is performed but I keep on getting error excessive pivot ratios (elements failed directions occur on rotational DOFs) . When I performed SOL 103 I got rigid body motions in rotational DOFs. Can anyone help me troubleshoot this problem? .bdf and f06 file has been attached for reference.
Do solid elements support application of MPCs?
