Does SLFFEA allow for hybrid elements like beam/shell combinations?
Not yet. The main issue is to coordinate all the DOFs, so that rotation and translation are correctly put into their components in the global stiffness matrix. To do this, I can imagine storing all the element stiffnesses in a big file, along with DOF data, and calling a global stiffness assembler which puts everything together. My code is currently more static than this, where each element stiffness is immediately put into the global stiffness so no copies exist(an exception is when I use the Conjugate Gradient method, but that’s another issue). This is a significant consideration. These files could get pretty big, and I currently want to prevent having to write out such data. If I ever do the multi-element code, I will try to keep this type of data in the program’s memory space, if at all possible. When I first began planning SLFFEA, I made the design choice to initially keep things simple. I thought I could go back and do the multi-element code one day, when I had finished doing the
