Sol 400 RBE3 with quadratic elemnts (ex. TET10).

Sol 400 RBE3 with quadratic elemnts (ex. TET10).

(OP)
Someone told me that to use a middle nodes (for quadratic element ex. TET10) as master in an RBE3 is non recommendable, especially in a sol 400 non-linear-static analysis, the solution might not converge.
Is it true and why???
Thanks

Best regards.
