| Apr 25, 2015 at 14:36 | comment | added | damian | Ah, I see. That's probably why it's not working. VegaFEM already implements homogenous boundary conditions by removing rows and columns from the simulation. I'm simulating non-homegenous displacement boundary conditions using PID controllers to apply external forces to the boundary nodes, but this introduces another kind of elasticity that I'd rather avoid. | |
