"Substitute equation 3 into 12" should be "Substitute equation 3 into 13"
Eqn. 11-10 2nd term's dz should be dx
Equation between 11-13 and 11-14 has the same error as 11-10
Eqn. 11-14 2nd line signs of 2nd and 3rd terms are reversed. Should be consistent wtih 11-15.
Eqns. 11-21 to 11-25 use e-bar with an i superscript. I think they shouldn't have the superscript and are the same 3 variables used in equations 11-26 and 11-28 without the i.
I think the first 3 rows of R_di in equation 11-30 should be negated. It looks like they come from the 4th terms in equations 11-15 which have a negative sign. This corrects some opposite sign displacements I was getting when I used the matrices directly.
p74 says "This is very different than the RBE3 which is a rigid element.". It should say RBE2, not RBE3.
p93 "Specify G1-G8 for a 4 node HEXA" should be 8 node.
p170 Default value for "CID Material coordinate system ID" is "0." but should be an integer without the ".".
p174 Format for RBE3 looks like it requires 3 grid points for WT1, 4 for WT2, and 2 for WT3. It's not clear that this is just an example and you can use different numbers. MSC puts "-etc.-" in some fields to show that.
In the RBE3 derivation section:

Apparently there should be 3 separate sums of weights WT, not just one like the manual shows. https://www.mystran.com/forums/showthread.php?tid=77&pid=287#pid287

Frequent use of "grid" instead of "grid point".
