Condensation of a Q8 serendipity FE to a Q4 FE with drilling DOFs?

Diego A. Alvarez @Diego-Alvarez-32

06 June 2024 1 882 Report

Hello,

Can somebody please give me some reference to a paper or book where it is explained how to condensate:

* from a Q8 serendipity FE to a Q4 FE with drilling DOFs (16 DOFs to 12 DOFs).

* from a H20 serendipity FE to a H8 FE with drilling DOFs (40 DOFs to 24 DOFs).

See the attached figures, taken from the RFEM technical manual.

Regards,

Diego Andrés
