These are the boundary conditions. Parallel to the space axis is for all 0 <= x <= L for a fixed time, i.e. initial conditions. > Would you prefer that I open an errata issue on > https://github.com/PetrKryslUCSD/FinEALE and add these there? > That would certainly work fine.

It does not have the same functionality, but close. My intention is to eventually wean myself off of Matlab for my own research and program my algorithms in Julia. So FinEALE is eventually going to be re-written in some way in Julia... In particular I am interested in solid shell elements at this point, and I also have a novel high-performance hex element in the current FinEALE. That will be ported soon, after I sort out how to avoid performance gotchas in Julia. Best regards, P > Rob J.
