This update is meant to significantly improve the RBE3 element implementation. The fix was achieved with two main changes to the RBE3_PROC code:
7d2f4bcc54bedd65f1d3e10898496de095425414 and 7d2f4bcc54bedd65f1d3e10898496de095425414 introduce new terms to the RMG matrix, the "S-terms" SXY, SZX and SYZ which lie in the lower-right partition of the Rdd matrix (refer to the manual, last page of Appendix E).
09b0b13556dec2b3e9f8e13517d2cc3bd39d98fa changes the way RMG is constructed so that per-DoF weights are used and eliminates divison by weight totals, preventing divide-by-zero errors.
